Transitioning Major Commercial Networks Between Providers?

Posted by Cliff on Tuesday August 27, 2002 @09:41AM from the switching-over-with-no-hiccups dept.

Kalon asks: "I am the network manager for a large business park connecting to our countries largest telco/ISP. We've recently negotiated to move our Internet services to another major provider and I'm stuck with a problem: our range of IP addresses (8 Class C's) is half 'owned' and half 'leased' from of our current provider. With some 90 companies relying on our connection for continuous Internet uptime, how can I transition forward and reverse DNS services for those companies with websites/mailservers unlucky enough to be on leased addresses, and route mapping for those whole blocks I own? Considering I don't have APNIC membership, what tips do you have to speed or ease the transition, considering I have to deal with lumbering telcos who won't play nicely together, and 90 different companies all demanding Internet presence?"

Make sure they are portable. by krangomatik · 2002-08-27 13:21 · Score: 2, Interesting

Check and make sure that the IPs that you "own" are in portable address space. I've known companies that have contractually "owned" IPs, but they were non-portable, so it didn't really do them much good.
