For example I do in Linux using
Host z.zzz.zz.z.in-addr.arpa. not found: 3(NXDOMAIN)
Then I repeat
host command in a reverse with
z.zzz.zz.z than I got a result of past
Host yy.yyy.yy.y.in-addr.arpa. not found: 3(NXDOMAIN)
What is occured and why is that result?
When I try got a WHOIS address of z.zzz.zz.z and yy.yyy.yy.y I got for example:
yy.yyy.yy.y --> KOREA NIC z.zzz.zz.z --> JAPAN NIC
A result via WHOIS is on properly address, but when I use
host command it result same.
For others who not understand my question look at this:
xx@yy:$ host 18.104.22.168 Host 22.214.171.124.in-addr.arpa. not found: 3(NXDOMAIN) xx@yy:$ host 126.96.36.199 Host 188.8.131.52.in-addr.arpa. not found: 3(NXDOMAIN) <--- Why 184.108.40.206 ? WHOIS don't respond this IP
