How is the IP of a nameserver located in it's own domain resolved?

Friday, June 16, 2017

I understand basics of how DNS works. My ISP finds out recursively, that my domain xyz.com is assigned with two nameservers:

ns1.xyzprivatens.com
ns2.xyzprivatens.com

Then it asks one of those two for the xyz.com IP and communicates with server using this IP.

Now is the interesting question. How IPs for the nameservers themselves are resolved?

Answer

This is done by means of the so-called Glue Records. More information here on SF or on Wikipedia.
