This is what I got:
C:\WINDOWS\SYSTEM32\>nslookup www.msgplus.net
Server: bsc2-s1.eastlink.ca
Address: 24.222.0.91
Non-authoritative answer:
Name: www.msgplus.net
Address: 66.220.17.175
Edit: I called my ISP, and they said it was Blacklisted or something. So I guess they banned it by mistake or something. I dunno. I still can't access it.
