Can you be more specific as to what IP's or blocks of IP's are blocked? When my host buys IP addresses they just give himPlea 5 IP addresses, often within the same block. So without knowing which IP address blocks are blocked, he could wind up moving my site to another blocked IP address. I have to purchase a new SSL Certificate each time I change IP addresses. This move is not free for me so I would like to do it only one time. Also, it would be interesting to see what sites are causing the problem. They might be hosted by Glowhost, in which case they could take action and fix the problem. Please let me know as soon as possible. I am loosing business ever day because of this. Robert
