Name Server Resource Record
The name server resource record (or glue record) describes the IP address of a name server associated with a (your) domain. This allows you to "find" the name server first.
Use 'Create/Change Nameservers' at 'My Domains' to create such records.
The contents of the name server or the "name server records" describe the services you offer, and the corresponding names and IP addresses for these services (e.g. 'www.my-sample-domain.com' has the IP address '192.168.1.1').
In case you chose Joker.com as your free name service provider, please click on 'DNS' at 'My Domains' to find all usable types of records.
