A couple of days ago, the name server for my site suddenly changed to something else. On my domain provider it is showing as the right one. For example this is what my domain registrar is showing<p>example.com ns7.abc.com <---------- this is the correct value<p>However, when I use nslookup, I am seeing something else altogether:<p>example.com dns1.xyz.com<p>My whois entry is indicating the incorrect value. The whois record continues to show the right owner of the domain though.<p>Has my domain been hijacked? How can I fix this?
If your domain registrar is showing the right name server then it should be okay. Try to contact the registrar and talk to them about the problem, They should be able to fix it.
It may also take some time for the DNS to set (aprox. 24 Hours).
