From the ARIN site:
"The name-based system of virtual webhosting used by many ISPs today allows multiple domains to be hosted by a single IP address. While some organizations use IP-based webhosting to, in part, justify their requests for IP space, ARIN will no longer accept IP-based hosting as justification for an allocation unless an exception is warranted. The ARIN Instructions for Using Name-based Virtual Webhosting may be a helpful tool in setting up, converting to, and using name-based hosting." Name-based virtual hosting does not work in many, MANY cases. Beyond this, if you have multiple customers on a single IP address and one of them is an idiot and spamvertizes their website, several providers have a policy of nullrouting the /32. Now, not only does it kill a single site but, potentially hundreds! --- John Fraizer EnterZone, Inc
