ARIN WHOIS database, last updated 2008-04-11 19:10
# Enter ? for additional hints on searching ARIN's WHOIS database.
Soon you'll learn who has control of their customers and who needs
firewalling. My experience with Mzima has been bad because their
customer Lunarpages seems to offer bulletproof spammer hosting on
occasion.
Anything involving China, Korea, Spain, Taiwan, Italy, Argentina, Egypt,
Romania, Turkey, Google, or MCI's old criminal cluster at 63.64.0.0/10
is probably best firewalled. The abuse address will probably bounce.
