Running dnsmasq as an authoritative DNS server
Your NS record for h.lohray.com is currently as follows:
h.lohray.com. 1800 IN NS 50.19.103.190.
Which is wrong. NS records should specify not an IP addresses, but domain names of a nameservers, like this:
h.lohray.com. 1800 IN NS h.lohray.com
h.lohray.com. 1800 IN A 50.19.103.190.
or like this:
h.lohray.com. 1800 IN NS ns.h.lohray.com
ns.h.lohray.com. 1800 IN A 50.19.103.190.
Your DNS server at 50.19.103.190 seems to work - it answers when I query of i7.h.lohray.com

Lord Loh. almost 2 years
I am trying to implement a dynamic dns service for my computers. I have pointed
h.lohray.com
to my EC2 instance in the NS record of lohray.com and have installed dnsmasq on that system and have made sure to unblock the firewall port.For now, I have statistically added an entry on my /etc/hosts file.
129.118.19.163 i7.h.lohray.com
however, i7.h.lohray.com does not resolve correctly with nslookup or dig :-( This is the only time I could have this resolved (online nslookup) - 50.19.103.190 is the IP address of the EC2 instance where dnsmasq is running. Where could I have gone wrong?

johnshen64 about 12 yearsi tried web dig, and here is the result for the authoritative dns server which i have added to my answer. it seems that the dns server is indeed set up, so it has to be something within you instance or ec2.

johnshen64 about 12 yearsgood news i have succeeded resolving it now. must be dns propagation. so it will take ttl time to propagate throughout internet (unless the dns servers that ignore ttl and cache records for longer). looks like your setup is correct. must be some sort of delay when i tested previously. sorry about that.

Lord Loh. about 12 yearsUnfortunately, I still get
i7.h.lohray.com IN NS 50.19.103.190 1800s (30m)
. I am expecting a different IP for i7.h.lohray.com. 50.19.103.190 is not the ip I set for i7.h.lohray.com in the hosts file :-( -

Lord Loh. about 12 yearsOh! I am sorry :-(. I think I read whatever was on my mind than what was on the screen :-( My shortcoming. When I query
50.19.103.190
fori7.h.lohray.com
, I get the right IP. I am still to figure out how to get the dnsmasq to resolve right. - Thank you. -
Sandman4 about 12 yearsUghm, you still seem to read whatever it is on your mind :). DNSMASQ DOES RESOLVE RIGHT. Your DNS server at 50.19.103.190 works OK.

Sandman4 about 12 yearsThe "bad" record resides on nsX.hostindia.net, which is probably your DNS hosting or registrar.
