Well I have also informed the host masters of COM.NP from my side.

The world of DNS is still new to me and I am picking the pieces from 
here and there.

I hope to gain more insight and knowledge in the field of DNS in the 
coming days ahead. And participating in this mailing list has truly be 
fruitful.

The host masters of COM.NP indeed seemed to have taken this matter 
seriously.

 From my network currently:

23:04:07 root at teklimbu:~$ check_soa com.np
         com.np. 86400   IN      SOA     shikhar.mos.com.np.

Unexpected response from 1 of 10 nameservers


Seems like the problem has been resolved for the time being!


By the way, thanks for your helpful and useful Generic NIC - sheets at:
