IP Allocation and Management?

jmw asks: "I work for a large[r] regional ISP in the midwest. In the past, and through several acquisitions, we've accumulated a substantial amount of IP space - non contiguous blocks from a /24 up to /19 or more, totaling several thousand IPs. With that many IP's, it's a fairly daunting task to manage, allocate and just keep track of what we have. I'm sure some of you are in, or have been in, similar situations... CVS has been used, but not standardized on.-More people would like to see a pretty web page or the like. For those of you in this situation, what have you done?"

[autocracy]

Create three basic classes of IPs (or whatever number suits you). Make a database to store it. Then set up calls to search by the IP you enter and have it bring up the block showing subnet mask, primary subdomain name, location, router, what part of the primary block it's in (IE if you divide up a /19 in /24s, you'll want to note it came from that higher-up block). You will want to maintain some uniformity in the size of the blocks you assign, because having /19s-/24s with constantly varyings masks will drive you up the wall no matter how much planning you use.
