What happened to Netsol redirection?

by

For as long as I can remember, netsol.com redirected to networksolutions.com, but recently that stopped. Netsol.com still resolves to an IP, namely 205.178.187.1,

> server 4.2.2.2
Default Server: vnsc-bak.sys.gtei.net
Address: 4.2.2.2

> netsol.com
Server: vnsc-bak.sys.gtei.net
Address: 4.2.2.2

Non-authoritative answer:
Name: netsol.com
Address: 205.178.187.1

but there’s no web server there:

Anyone know the reason for the change?
