I'm in the process of setting up my own name servers using BIND9, however I want to visualize the name server setup in relation to registrars and other name servers.
Say I have a domain
I setup my 2 name servers:
1) How does the world know that my name servers are now at
ns2.mydomain.com? I read about setting up glue records at my registrar. Could you please elaborate on this, i.e. once i setup these glue records, can I now use my name servers in NS records for any other domain?
For e.g. NS records for
2) Given I setup the glue records as mentioned above, do I "have to" update
mydomain.com NS records to point to my name servers? Can I keep mydomain.com NS records pointing to my registrars name servers, however use
ns2.mydomain.com as name servers for any other domain I own?
