This question already has an answer here:
I am trying to build my own DNS. I have one server which I would like to use as DNS server.
- Why, according to RFC2182 section 5 (https://tools.ietf.org/html/rfc2182#section-5) I must have TWO servers (3 recommended)?
I tried creating ns1.example.com and ns2.example.com pointing to same IP and it works for some TLDs fine but for my .us domain it doesn't open the website.
- Why some TLDs does not work with just one server (two ns pointing to same IP)?
Sorry if the quiestion is boring. Thanks!
