Child Name Servers are Name Servers which are registered with the Registry under your domain name. You have to register Name servers with the Registry, before you can use them as Name Servers for registering other domain names. Child Name Servers can be registered only by the owner of the domain name under which they are registered.

Example:

A Child Name Server ns2.xyz.com can only be registered by the Owner of xyz.com.

Registering and Managing Child Name Servers

1. Login to your Control Panel, search for the domain name and proceed to the Order Information view. 1

   Note

   • If the domain name is Locked/Suspended, you will have to first get it Unlocked/Unsuspended it before proceeding further.

   • For Resellers: If the domain name is Locked by you, you may proceed without Unlocking it.

   • For Resellers: If the domain name is Locked by ABC DIGITAL WEB SOLUTIONS, LLC., you need to get it Unlocked first. Contact our Support Team at http://www.abcdigital.info/index.php/page/content/action/3.

   • For Resellers: If the domain name is Suspended by either you or ABC DIGITAL WEB SOLUTIONS, LLC., it needs to be first Unsuspended, before you can proceed.

2. Click the Child Name Servers link. Here, you may:

   Add a Child Name Server ^{(Anchor: add)}

   Enter the Host Name of the Child Name Server you wish to add in the Host Name box, mention its IP Address (IPv4 or IPv6) and click the Save button.

   Examples:

   • For yourdomainname.com, you may use the Host Name as ns1.yourdomainname.com and an IPv4 IP Address as 111.222.333.444.

   • yourdomainname.biz could have the Host Name as dns1.yourdomainname.biz and an IPv6 IP Address as 2001:0db8:0:0:0:0:1428:57ab.

   Note

   • Generally, a domain name may have any number of Child Name Servers associated with it.

   • You will encounter the below error message in case an invalid or reserved IP Address is used:

     Attention

     Additional Information

     IPv4 Address Space

     IPv6 Address Space

   • An IPv6 Address may be entered in either of the following formats:

     • 2001:0db8:0000:0000:0000:0000:20.40.87.171

     • 2001:0db8:0000:0000:0000:0000:1428:57ab

     • 2001:0db8:0000:0000:0000::1428:57ab

     • 2001:0db8:0:0:0:0:1428:57ab

     • 2001:0db8:0:0::1428:57ab

     • 2001:0db8::1428:57ab

     • 2001:db8::1428:57ab

   • IPv6 Addresses are not supported for some TLDs:

     • .NZ

     • .WS

     • .NAME

     • .CO

     • .CA

     • .DE

     • .ES

     • .RU

   • Registering a Child Name Server as mentioned above is just the first step. The Child Name Server is required to be registered at the Registry to only serve as a non-authoritative Record should your Child Name Server not be resolvable in some extreme condition.

     This Name Server would start working only after you have added either an Address (A) Record for IPv4 or AAAA Record for IPv6 or Canonical (CNAME) Record for this Name Server within the Zone for the domain name (of this Child Name Server) in your own DNS Server, thus binding the NS to the IP Address.

     Examples:

     • If you are running your own DNS Servers, then you would need to add a Zone for the domain name yourdomainname.com and create an A Record like:

       ns1.yourdomainname.com. 38400 IN A 111.222.333.444

       Similarly, you may add an AAAA Record as

       ns1.yourdomainname.com. 38400 IN AAAA 2001:0db8:0:0:0:0:1428:57ab

     • If you wish to simply point your Name Servers to other Name Servers, then you may do so by either:

       1. you may either add a CNAME Record to your Service Provider's Name Server, after enabling Managed DNS service through them:

          ns1.yourdomainname.com. 38400 IN CNAME ns1.serviceprovider.com

          or

       2. you may add an A or AAAA Record to your Service Provider's Name Server IP Address (depending upon whether your Service Provider has an IPv4 or IPv6), after enabling Managed DNS service through them:

          ns1.yourdomainname.com. 38400 IN A 777.888.999.000

          or

          ns1.yourdomainname.com. 38400 IN AAAA 2001:0db8:0:0:0:0:1428:57ab

   • Generally, each Child Name Server may have upto 13 unique IP Addresses associated with it.

   • For CentralNic ^{(Anchor: crules)} domains, each Child Name Server may only have a single unique IP Address associated with it.

     Additional Information

     Identifying CentralNic Domains

   • In case of .EU domain names ^{(Anchor: eurules)}, all Child Name Servers that you create/add, are automatically associated with that .EU domain name as a Name Server. Due to this limitation, you will only be able to add upto 9 Child Name Servers for .EU domain names.

     The maximum number of Name Servers that can be associated with any .EU domain name is 9. If you have already added other Name Servers (not Child Name Servers of this .EU domain name), then the number of Child Name Servers that you may create would reduce by that many.

     Additional Information

     Changing Name Servers of a Domain Name

     Examples:

     • yourdomainname.eu

       Child Name Servers created: ns1.yourdomainname.eu and ns2.yourdomainname.eu

       These Child Name Servers get automatically added as Name Servers as well for this domain name: ns1.yourdomainname.eu and ns2.yourdomainname.eu

     • yourotherdomainname.eu

       Name Servers used: ns1.hostingprovider.com, ns2.hostingprovider.com

       Child Name Servers created: ns1.yourotherdomainname.eu, ns2.yourotherdomainname.eu

       These Child Name Servers get automatically added as Name Servers for this domain name: ns1.yourotherdomainname.eu, ns2.yourotherdomainname.eu

       So in all 4 Name Servers will be associated with yourotherdomainname.eu: ns1.hostingprovider.com, ns2.hostingprovider.com, ns1.yourotherdomainname.eu, ns2.yourotherdomainname.eu

       This means that now for the domain name yourotherdomainname.eu, you may only add upto 5 other Child Name Servers or Name Servers since every time you create a Child Name Server, it gets automatically associated with the .EU domain name as a Name Server.

     Apart from the above, in case of .EU domain names, each Child Name Server may have upto 9 unique IP Addresses associated with it.

     Example:

     You can Registrar a Child Name Server with the Host Name ns1 for yourdomainname.eu and associate upto 9 unique IP Addresses with this Host Name.

   • In case of .UK domain names ^{(Anchor: ukrules)}, all Child Name Servers that you create/add, are automatically associated with that .UK domain name as a Name Server. Due to this limitation, you will only be able to add upto 10 Child Name Servers for .UK domain names.

     The maximum number of Name Servers that can be associated with any .UK domain name is 10.

     If you have already added other Name Servers (not Child Name Servers of this .UK domain name), then the number of Child Name Servers that you can create would reduce by that many.

     Additional Information

     Changing Name Servers of a Domain Name

     Examples:

     • yourdomainname.uk

       Child Name Servers created: ns1.yourdomainname.uk and ns2.yourdomainname.uk

       These Child Name Servers get automatically added as Name Servers as well for this domain name: ns1.yourdomainname.uk and ns2.yourdomainname.uk

     • yourotherdomainname.uk

       Name Servers used: ns1.hostingprovider.com, ns2.hostingprovider.com

       Child Name Servers created: ns1.yourotherdomainname.uk, ns2.yourotherdomainname.uk

       These Child Name Servers get automatically added as Name Servers for this domain name: ns1.yourotherdomainname.uk, ns2.yourotherdomainname.uk

       So in all 4 Name Servers will be associated with yourotherdomainname.uk: ns1.hostingprovider.com, ns2.hostingprovider.com, ns1.yourotherdomainname.uk, ns2.yourotherdomainname.uk

       This means that now for the domain name yourotherdomainname.uk, you can only add upto 6 other Child Name Servers or Name Servers since every time you create a Child Name Server, it gets automatically associated with the .UK domain name as a Name Server.

     Moreover, in case of .UK domain names, each Child Name Server can have only a single unique IP Address associated with it.

     Example:

     You can Registrar a Child Name Server with the Host Name ns1 for yourdomainname.uk and associate only a single unique IP Address with this Host Name.

   • Child Name Servers can not be created under a .TEL domain name ^{(Anchor: telrules)}, due to restrictions placed by the Registry.

   • A .CN domain name ^{(Anchor: cnrules)} can only have upto 6 Child Name Servers associated with it and each Child Name Server can have only a single unique IP Address associated with it.

     If a particular IP Address is already associated with any other .CN domain name's Child Name Server registered through any Registrar, then it can not be used with any other Child Name Server under any other .CN domain name.

     Examples:

     • You may Registrar a Child Name Server with the Host Name ns1 for yourdomainname.com.cn and associate 66.11.11.11 with it. This Child Name Server would be created only if the IP Address 66.11.11.11 is not already associated with any other .CN domain name's Child Name Server registered through any Registrar.

     • Once you have registered a Child Name Server with the IP Address 66.11.11.11 for yourdomainname.com.cn, you may add only 5 other Child Name Servers under this domain name but none of the remaining 5 can be registered with 66.11.11.11 (since it is already used).

   • The total number of Name Servers and Child Name Servers taken together should not exceed 10 in case of .NZ domain names ^{(Anchor: nzrules)}.

     Examples:

     • Consider a domain name yourdomain.co.nz with Name Servers as ns1.yourdomain.com and ns2.yourdomain.com. The total number of additional Name Servers that can be added under yourdomain.co.nz alongwith any Child Name Servers that can be created under yourdomain.co.nz will be 8.

     • On a similar note, a domain name yourdomain.co.nz is using its own Child Name Servers ns1.yourdomain.co.nz and ns2.yourdomain.co.nz as its Name Servers as well. Here, the total number of additional Name Servers that can be added under yourdomain.co.nz, taken together with any new Child Name Servers created under yourdomain.co.nz will be 6.

     Moreover, each Child Name Server under a .NZ domain name can have only 1 IPv4 Address associated with it.

     Example:

     You may Registrar a Child Name Server with the Host Name ns1 for yourdomainname.co.nz and associate only a single IP Address of the form 66.11.11.11 with it.

   • Each .DE domain name ^{(Anchor: derules)} needs to have at least 2 Name Servers and can have upto 13 Name Servers. The limitation of supporting a maximum of 13 Name Servers is common for both Child Name Servers and Name Servers.

     Examples:

     • If you add 4 Name Servers for your .DE domain name, then you may now add only upto 9 Child Name Servers or Name Servers.

     • If you add 2 Name Servers and 2 Child Name Servers for your .DE domain name, then you may now add only upto 9 Child Name Servers or Name Servers.

     The first three segments of the IPv4 (IP) address of at least 1 Name Server (either Child Name Server or Name Server) needs to be different from the others.

     Examples:

     • If you try adding 4 Name Servers - ns1.hosting.com, ns2.hosting.com, ns3.hosting.com, ns4.hosting.com for your .DE domain name and if their individual IPv4 addresses are 67.15.253.220, 67.15.253.221, 67.15.253.222, 67.15.253.223, then you will get an error since the first three segments no single IP address is unique.

     • If you add 2 Name Servers (ns1.hosting.com, ns2.hosting.com) and 2 Child Name Servers (ns1.myname.de, ns2.myname.de) for myname.de and if their IPv4 addresses are 67.15.253.220, 67.15.253.221, 67.15.253.222, 74.54.56.236, then you will not get an error since at least 1 IP address has its first three segments unique.

     To add a Child Name Server for your .DE domain name, you need to follow the below mentioned process:

     • In the Zone of your .DE domain name, add an Address (A) Record for the first Child Name Server that you plan to submit for your .DE domain name.

     • Repeat the above two steps for any number of Child Name Servers that you wish to add.

     If you plan to use your Child Name Servers as your Name Servers, you would need to create NS Records for the same, before modifying the Name Servers.

     Example:

     If you add 2 Child Name Servers ns1.myname.de and ns2.myname.de for myname.de, then prior to using them as Name Servers of myname.de, you need to ensure that you add ns1.myname.de and ns2.myname.de as NS Records.

     .DE domain names do not support IPv6 addresses.

   • In case of .ES domain names ^{(Anchor: esrules)} you may associate only a single IPv4 Address per Child Name Server.

   • In case of .RU ^{(Anchor: rurules)} domain names, the same IP Address can not be reused for another Child Name Server.

   Modify a Child Name Server ^{(Anchor: modify)}

   Note

   .AU domain names do not support modification of a Child Name Server. You need to instead delete the existing Child Name Server and add another.

   • Modifying the Hostname: Make the modifications in the Host Name textbox and click the Save button.

     Note

     If you modify the Hostname of a Child Name Server under a .NZ domain name, you need to manually make necessary modification to the domain name(s) using the original Child Name Server.

     Example

     Consider a domain name yourdomain.co.nz with a Child Name Sever as ns1.yourdomain.co.nz, which is being used as a Name Server for yourdomain.co.nz. If you modify the Hostname for ns1.yourdomain.co.nz from ns1 to ns2, you need to manually modify the Name Server for yourdomain.co.nz from ns1.yourdomain.co.nz to ns2.yourdomain.co.nz.

   Delete a Child Name Server ^{(Anchor: delete)}

   Click the Delete link to delete individual Child Name Servers.

   Note

   You will encounter the below error message while deleting a Child Name Server if this is being used by another domain name of the same extension as a Name Server:

   Attention

   Object association prohibits operation

   Example:

   If the Child Name Server ns1.yourdomainname.com is being used by xyz.com as its Name Server, then you will not be able to delete ns1.yourdomainname.com until xyz.com modifies its Name Server (to some other Name Server).

   You will need to modify the Name Servers of all domain names using the Child Name Server as their authoritative Name Server and try attempt the Child Name Server deletion.

   However, if xyz.info was using ns1.yourdomainname.com as its Name Server, then you would not face any issue while deleting your Child Name Server: ns1.yourdomainname.com.
