I've got one domain name and I want to set it up for my hosted site on Github Pages service. In the documentation this point is mentioned that
If you are using a top-level domain like example.com, you must use an A record pointing to 22.214.171.124.
But my domain registrar doesn't permit me to add a DNS Record. But only asks me to fill one table like this:
Name Server (NS Record)
Server Name ......... | Server IP
ns53.parsihost.com | 126.96.36.199
ns2.parsihost.com | 188.8.131.52
I asked the registrar about this problem and they said to me "You must put Github's name server in those cells". So, what is the mapping from this table to DNS Records, and what is your advice for filling this kind of table?
