I'm trying to set up a DNS to complement the DNS provided by my hoster (see also this related question). Now I don't seem to understand my domain's DNS record, which is this (some entries omitted for brevity):
econemon.com. 1800 IN NS ns.stratoserver.net. econemon.com. 1800 IN NS ns2.stratoserver.net. econemon.com. 1800 IN A 18.104.22.168
Now, I don't really grok two things, despite reading up on DNS in Wikipedia:
- Why does the nameserver, in addition to the A record, return an NS record pointing to itself? What would that be used for? My understanding was that this record would be delivered by a name server which is not responsible for the domain.
- How exactly does the client use the two NS records? Can I add more, and what is the point?
