242337 - PAC2: myIpAddress() should be replaced by a myIpAddresses()

Status: RESOLVED WONTFIX

(Core :: Networking, defect)

Description

[benc]

This is part of "PAC2", a set of bug reports that will be useful for the
now-hyopthetical, but almost-inevitable re-write of PAC.

From looking at the PAC spec, it seems clear that we cannot make myIpAddress
return multiple addresses, because existing PAC files assume it is a single address.

We probably need to change it so it can support a list of addresses, and perhaps
change the orientation of the service to "is my IP address w.x.y.z?" so that PAC
writers do not need to all worry about learning new javascript logic. (As a
Proxy admin, I limped along for years w/o knowing any substantive javascript,
and I imagine there are still many like me).

bug 347307 adds support for this to the DNS service, at least for unix/macos.

Other browsers seem to use myIpAddressEx() to fix this problem
