Everyone is new here once, some people go away and come back and find out things have changed on Undernet. These tips should be helpful for those new to IRC, new to Undernet and those returning after a period of time. Of course, if you have any questions, we are always happy to meet you and help you in #mIRCHelp on Undernet!


Basic Undernet Information:

Undernet is one of the largest Internet Relay Chat networks in the world, with nearly 30 servers connecting over 1,000,000 people a week.

Undernet offers username registration and channel registration. It does NOT offer nickname registration. Nicknames are on a first come, first served basis. Anyone may use any nickname they choose as long as it is not being used by another user at the time. Undernet limits nicks to 12 characters in length. Since nicks are not owned, Undernet offers username registration for identification.

Username Registration:

A registered username allows you to identify yourself to X. (X is the channel service bot given to registered channels on Undernet and managed by CService.) It is not nick registration. Usernames are used for:

  • channel access via X
  • logging in to the CService website
  • joining +r (Registered Users Only) channels
  • setting your usermode to +x (Virtual Hostmask)
  • supporting a channel during the registration process
  • implementing X commands

If none of these apply to you then you do not need to register a username. A username cannot be changed, although you may change and are encouraged to change your password frequently. The policy on Undernet is ONE username per person.

If you would like to register a username for undernet's channel services, go to http://cservice.undernet.org/live and click on the Register! link. You must provide them with a real ISP email address, like one provided to you by your Internet Service Provider; they don't accept hotmail, yahoo or most other free web-based emails for registration purposes.

Once you have registered a username, you can log in to X by typing: /msg X@channels.undernet.org login Username Password (Be aware, you must log in at least every 60 days or your username will be purged.)

You can put this command in mIRC (View/ Options/ Connect/ Options...Perform tab) to log in automatically when you connect. (Make sure you select Undernet as the Network.)

If you have access to a channel, X will op you after you have logged in when you type: /msg X op #channelname nick

Undernet has a channelmode +r. Only registered users who are logged in can join those channels set +r. (Ops can bypass this restriction by inviting a user in who is not logged in to a registered username.)

Undernet also has a usermode +x. It allows logged in users to hide their real host, replacing it with @username.users.undernet.org. In order to use this mode, log in to X then type: / /mode $me +x or /mode nick +x

New in December, 2005: NOADDUSER command: /msg X set noadduser on/off. If set on, this command keeps others from giving access to you without your knowledge.

Channel Registration:

Undernet offers Channel Registration for established channels. Channel registration is not meant as a means to start a new channel. It is meant for previously established channels to have an opportunity to have some stability. If you are beginning a new channel, then just start using your channel and give it time to see if a reasonable userbase develops to justify registration. Once you have an established channel with at least 5 people (this was changed from 10 people in July, 2013) with registered usernames at least 3 days old who regularly visit your channel and support you as the channel manager, you may submit a channel registration application. You must wait 5 days (this was changed from 10 days in July, 2013) after registering a username in order to submit a channel registration request. To submit a channel registration request for an established channel, go to http://cservice.undernet.org/live/ , log in with your username and password, then click on Register A Channel. You will need the registered usernames of 5 supporters from your channel. It will take about 10 days to be approved or rejected. Click the Check App link to check the status of the registration process on the CService site.
