There are quite a few IPs:
# host www.myspace.com
www.myspace.com has address 216.178.39.14
www.myspace.com has address 216.178.39.15
www.myspace.com has address 216.178.39.16
www.myspace.com has address 216.178.39.74
www.myspace.com has address 216.178.38.129
www.myspace.com has address 216.178.38.130
www.myspace.com has address 216.178.38.131
www.myspace.com has address 216.178.39.11
www.myspace.com has address 216.178.39.12
www.myspace.com has address 216.178.39.13

I can elinks to http://www.myspace.com with no problems, however 
traceroute doesn't make it, so they must be filtering ICMP:

If I use TCP SYN method, I get there fine:
