My proxy.pac stopped working in the 2002031312 build. Apparently this is due to
myIpAddress() having gone haywire. It used to return my IP address. Now it
returns "::ffff:xxx.xxx.xxx.xxx" where the xxx's represent my address. The
colons and 'ffff' are something I've never seen before (and they aren't there in
the Windows version of the same build). This caused my proxy logic to break
since my IP address was malformed. 
A rewrite of the script to discard leading garbage helps, but I have no idea
what's going on.
Neil, 0.9.9 isn't really the newest version, cound you try 1.0RC1 or maybe a
recent nightly?
+ regression, 4xp, mozilla1.0

(wonders if this is an IPv6 address format?)

please post a small PAC file that shows this problem as an attachment.

linux-only (so far) -> pp, helpwanted to get attention.
that looks like IPv6 to me...

hmm.. yeah, it probably makes sense to return the address as an IPv4 address
literal if the address is merely an IPv4-mapped-IPv6 address.  i wonder what the
standard for PAC says.

PAC never envisioned support for IPv6. It is like most network address layer
protocols, it needs to be extended (and possibly re-purposed) for the new new
networking world.

since myIPAddress calls Resolve, this is a duplicate of bug 191715.

RESOLVED/FIXED (per Darin).

However, on my Mac, I seem to only get back 127.0.0.1 even though my mac has
IPv4 and IPv6 addresses on the ethernet interface.

Darin:

in bug 191715, are you converting only IPv6 addresses to IPv4 that can be
mapped? What happens to IPv6 addresses that are untranslatable? Do you return
the IPv6 values?
