our internal IP routing data base, and because I have participated
in Ingres development here in Russia in RUBIN/DEMOS project -
through it was not freeware work - and it was very interesting for
me too see such good freeware data base as PostgreSQL), and I
modified 'ipaddr' data type library in accordance to our requests
and to allow SQL do indexing over ipaddr objects.
You can read description at 'http://relcom.EU.net/ipaddr.html' and
get sources at 'http://relcom.EU.net/ip_class.tar.gz'. It contains
sources, sql scripts for incorporating new data type into postgres
(including ipaddr_ops operator class incorporation) and 20,000
records based data test for the indexing.
I am not sure if it's proper mail list for this information, and
if it's interesting for anyone except me to get full-functional
ipaddress class. I am ready to make all modifications, bug fixing
and documentation for this data class if it's nessesary for it's
contribution to the Postgres data base.
Anyway, all my work was based at original 'ip&mac data type'
contribution, written by Tom Ivar Helbekkmo.
Be free to write me any questions or requests about this work.

This patch fix the Makefiles in contrib/{pginterface, spi,
miscutil, int8, ip_and_mac, sequence, soundex, string, userlock,
array, datetime} to install their modules in one directory(lib/modules/).
implementation that's in contrib/ip_and_mac/. This one works right
with 6.3, avoids the problems I ran into earlier with LIKE, and
includes a bit of extra functionality.

PostgreSQL type extensions for IP and MAC addresses.
I needed to record IP and MAC level ethernet addresses in a data
base, and I really didn't want to store them as plain strings, with
no enforced error checking, so I put together the accompanying code
as my first experiment with adding a data type to PostgreSQL. I
then thought that this might be useful to others, both directly and
as a very simple example of how to do this sort of thing, so here
it is, in the hope that it will be useful.
