Hi Tom, Sander Steffann [EMAIL PROTECTED] writes: From: Harald Fuchs [EMAIL PROTECTED] Forget inet. Check out http://pgfoundry.org/projects/ip4r/ and be happy. I would be happy if it would support IPv6 :-) Are there plans to make ip6r or something like that? What's the point? You might as well use the regular inet type if you need to handle ipv6. Well, the OP said to forget about inet, and I like the ip4r range type. I hoped there was something better/nicer/shinier :-) Thanks, Sander ---(end of broadcast)--- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match

You might as well use the regular inet type if you need to handle ipv6. ip4r's main advantage over inet is that it allows you to answer the question is this IP address in any of these large number of address ranges efficiently. It's useful for customer address allocation, email filtering blacklists, things like that. A range-indexable ipv6 type would be useful in theory, but I've not seen a need for it in production yet. When there is, extending ip4r to become ip6r would be possible.

It's kind of ridiculous how much work goes away in my code. Too bad I can't do this at work (Oracle 8/9).

[GENERAL] IP addresses
I am planning on doing a LOT of work with ip addresses and thought that the inet data type would be a great place to start. But I'm not sure how this works in with accessing the addresses. In perl or ruby how is the value returned? Or should I stricly use host() and other functions to be explicit about what I'm doing. Another question. Given a subnet (eg: 192.168.1.0/24) is there some way to pull all the addresses therein? I can do this in code - but I was curious if there was a postgres way of doing it (didn't see any, but..)
