Are there any "good" tools for IPv6 address management?
Is there a "BCP" (convention, whatever) for storing IPv6 addresses into SQL databases? Particularly where you need to mix them with IPv4 addresses. I know postgresql has an ipv6 type but I was hoping for something more portable. The best I could come up with was packed decimal(39) and assume that if more than 32 bits are set it's IPv6 (ignoring the special case of all zeros etc.) The other would be to just use 4 unsigned long ints similarly but it makes comparison and other ops clunky. -- -Barry Shein The World | bzs@TheWorld.com | http://www.TheWorld.com Purveyors to the Trade | Voice: 800-THE-WRLD | Login: Nationwide Software Tool & Die | Public Access Internet | SINCE 1989 *oo*

PostgreSQL supports this. Check out the data types. (yes, 8.2 is the latest, but google to the first hit is easier) http://www.postgresql.org/docs/8.0/interactive/datatype-net-types.html#DATAT...

um, lots of folks have written modules for almost every language to do ip/subnet comparisons for both v4 and v6. While I can understand the desire to use locally derived code, etc.. it does make sense to not reinvent the wheel daily :) OT: Speaking of which, someone know of something like the multicast beacon software that works for unicast stuff that is "free"? I've wanted to make some udp-like probe matrix like this and with all the folks that are asking about cogent, l3, etc.. outages was thinking that a user community of this type of a test matrix could be interesting :) Think like the "internet health report" but with more sites (possibly hundreds). - jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.

I am a PostgreSQL weenie, I admit, but if you can at all use it, I strongly suggest you use the inet and cidr datatypes in PostgreSQL for this. Alternatives often give up the data rigour that you get from a datatype. Portability is often a target that forces you to give up all the nice features that you got when you chose your RDBMS. I suppose in other systems, you could put a trigger on a varchar() or whatever field that would validate the address on the way in. That's what I'd do if I had to give up the datatype.
