Hello,

Was fiddling around with something, and in in tcl-commands.doc I found the
myip command.
Tried this, from partyline:
.tcl putserv "privmsg mynick : [myip] "

and the bot promptly sent me a ten digit number.

What is it? some sort of encoding of the bot's true ip number?


Thanks

It is the 32bit representation of your IP-address. Given the IP-address aaa.bbb.ccc.ddd, the 'long-IP' would be (2^24)*aaa+(2^16)*bbb+(2^8)*ccc+ddd.

Thanks for explaining.

It is interesting. How would one make use of it though?

You may convert it into normal ip useing this proc from fsck function library v1.19 by perpleXa:
Code:
# longip: Converts the long value of an ip to it's dotted quad ip.
proc longtoip {long} {
  format "%u.%u.%u.%u" [expr $long>>24] [expr ($long>>16)&255] [expr ($long>>8)&255] [expr $long&255];
}

willyw,
One of the main uses for the 'longip' version with eggdrops are for dcc chat/send requests
