[NMLUG] Minimal IP address reflector

[kelly.terry.jones at gmail.com (Kelly Jones)]

There are several websites that will "reflect" your IP address
(whatsmyip.org, whatismyipaddress.com, auditmypc.com/whats-my-ip.asp,
showipaddress.com, and even things like secure order pages,
etc). You can even get this info from some MediaWikis if you're not
logged in:

However, all these pages return lots of extra junk, not to mention
HTTP headers, etc. Is there a "minimal" IP address reflector where I
could maybe telnet to a port on a given host and see my IP? Something
like the daytime service [port 13] NIST offers for the current time
(or time [port 37] service for binary data):

> telnet time-a.nist.gov daytime
Trying 129.6.15.28...
Connected to time-a.nist.gov.
Escape character is '^]'.

54309 07-07-28 16:59:56 50 0 0 523.2 UTC(NIST) *
Connection closed by foreign host.

only for IP addresses? I realize I could write one myself, but am
looking for an existing service.
