nslookup does not work on certain IP address [closed]
when I gave nslookup 74.125.236.200
Server: 192.168.5.11 Address: 192.168.5.11#53
Non-authoritative answer: 200.236.125.74.in-addr.arpa name = maa03s17-in-f8.1e100.net.
Authoritative answers can be found from: 125.74.in-addr.arpa nameserver = ns3.google.com. 125.74.in-addr.arpa nameserver = ns1.google.com. 125.74.in-addr.arpa nameserver = ns4.google.com. 125.74.in-addr.arpa nameserver = ns2.google.com. ns3.google.com internet address = 216.239.36.10 ns2.google.com internet address = 216.239.34.10 ns4.google.com internet address = 216.239.38.10 ns1.google.com internet address = 216.239.32.10
But when I gave nslookup 1.0.0.245 I got the below reponse
Server: 192.168.5.11 Address: 192.168.5.11#53
** server can't find 245.0.0.1.in-addr.arpa.: NXDOMAIN
But for the both above mentioned IP addresses I am able to find the domain name details when I used IP2Locations
It just happens that there is no reverse DNS record defined for this particular IP address, so nslookup
can't find anything.
