Re: LuaSocket: find out current IP address

[Jon Nalley <lists@...>]

One other nice thing about OpenDNS is that you can simply do a reverse
lookup on myip.opendns.com to get your IP address.

This can be accomplished from luasocket using the following:

require("socket")
myip = socket.dns.toip("myip.opendns.com")

Keep in mind the host running the above code must be using the OpenDNS
nameservers for DNS.  The IP's of the OpenDNS servers are:
208.67.222.222 and 208.67.220.220
