[tor-bugs] #3982 [Tor Client]: MAPADDRESS for IP ranges (CIDR, etc)
#3982: MAPADDRESS for IP ranges (CIDR, etc)

-------------------------+--------------------------------------------------
The general idea is to have MAPADDRES match blocks of IP addresses with
one rule:
MAPADDRESS 1.2.3.4/18 1.2.3.4/18.<fingerprint>.exit
Very useful for:
o Same as domain wildcarding...
o Constraining known destination ranges to an exit. VPN's, corporate/edu
DMZ's, location aware services, location/IP restricted services, etc.
o Catchall for unexpected/unknown use of IP's. Such as websites that code
them in html page elements, services such as multimedia farms, places that
don't use FQDNS, etc. If you know one IP (manual resolve, or see one pop
up), you can MAP out a good sized CIDR block without disturbing your other
Tor traffic.
o Simplicity, fewer MAP rules.
Further rationale, examples and extensions...

"[We] need to figure out (or somebody else would figure out) how this
would interact with DNS resolution. :)" --NickM
It's already figured out... DNS is just a user/app layer on top of Tor's
network transport, and thus DNS is not involved :)
Tor just needs to grab whatever IP's the client ultimately requests to get
to via SOCKS/TransPort (if and after any DNS [resolved via SOCKS, the
host, or otherwise]), and route them through the MAPPED exit... if the
user specified such a MAP for said IP's.
