IRCX defines a user mask as follows:
NickName!UserName@HostName$ServerName
Chat Service interprets special characters in user masks according to the following table.
| ! | Specifies that what follows is a user name. |
| @ | Specifies that what follows is the domain name or IP address of the computer hosting the client. |
| $ | Specifies that what follows is a server name. |
| . | A string containing a period is interpreted as a domain name. |
| * | Wildcard character used to match any number of characters. |
| ? | Wildcard character used to match one character. |
Note The identification (using the Ident command) of an anonymous user begins with a tilde (~) so that you can filter anonymous users.
|
| Makes the user with the nickname Piper
the host of #MyChannel. "Piper" is interpreted as
"Piper!*@*$*". Note A string without the special characters !, @, and $ is interpreted as a nickname. |
|
| Starts monitoring all events generated by users at the site nwtraders.microsoft.com. "nwtraders.com" is interpreted as "*!*@nwtraders.microsoft.com$*". |
