I've seen numerous irc servers that when you do /server irc.domain.com without specifying a port, it automatically redirects you to a non-default (something other than 6667) port, or where it redirects you to a random port. Any idea how to go about doing something like that?
irc.cyanide-x.net for example..
/server irc.cyanide-x.net
* Connecting to irc.cyanide-x.net (6806)
* Connect cancelled
/server irc.cyanide-x.net
* Connecting to irc.cyanide-x.net (6907)
* Connect cancelled
/server irc.cyanide-x.net
* Connecting to irc.cyanide-x.net (6945) |

the owners either don't have their name servers setup correctly, or they have put random ports in deliberetly.
try contacting them to see.
if all else fails, try using /server server.name:port (if on mIRC)
for xchat, etc. use: /server server.name port |

| That's not what I was looking for. I'm wondering HOW they set it their DNS up to point to a port as well like that. |

DNS has nothing to do with ports. DNS is domain name service, which means it does nothing but give names to numbers. The IRCd must listen to ports on the IP that resolves from the name entry. You can't specify ports at all in the DNS server config file as far as zones goes. They submitted their ports incorrectly to the client author.
For example they have ports 6667-7002 from mIRC.
Try /server irc.cyanide-x.net 6667 which I've connected to just fine using it.
both server:port and server port work in mIRC. |

You can setup ports in your DNS, (DNS Port Redirection), It's done on the DNS server's side, I've done it before  |

perhaps .. but 99.9999% of the other irc networks don't and it's not required. I seriously doubt there is a good reason to use DNS Port Redirection on a network that uses software that can take advantage of multiple A records as well as binding to multiple ports and I think that the answer is far more simple than port redirection.
The case here is most likely the network meant to submit something like 6667-6669, 7002 not 6667-7002. Just a simple typo in a submission form. |
