Re: POP relocation [7:9897]
Since you did not mention for sure whether you would switch ISP or not. 1. If you stay with the same ISP, they should be able to let you keep the same IP number especially for those 2 /24s. If they plan everything ahead of time and you keep the old IPs, it is indeed only going to be couple minutes of downtime and you don't have to do anything on your router. Of course, this is based on the assumption that they have good network engineers over there taking care of your case. 2. If you are going to switch to another ISP, you would probably have to change your IPs since you don't own those /24s. Theoretically, those two ISPs could make arrangements to let you keep the old IPs. However, it is going to be a big hassle and you would find it not worth the effort.

RE: POP relocation [7:9897]
Why not renumber now and use NAT/PAT and then only renumber your serial interfaces on your Internet Router and gateways and mail servers after the switch??? -Original Message- From: Richard Chang [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 26, 2001 1:04 PM To: [EMAIL PROTECTED] Subject: Re: POP relocation [7:9897] Since you did not mention for sure whether you would switch ISP or not. 1.
