Mask item

In the configuration file there are various places where you can use a mask. A mask defines which host/IPs/users should be matched.

One or more mask entries
If you only need to match 1 entry then you can use the simple variant, eg: mask 127.*;

If you want to match multiple items, or if you just prefer this style, then you can use a list: mask { 10.*; 192.168.*; 127.0.0.0/8; }

Extended matching
In UnrealIRCd 5.2.1 and later Extended server bans syntax is also supported. This way you could, for example, add a second allow block with: allow { mask ~a:TrustedUser; class clients; maxperip 10; } If TrustedUser is identified to services using SASL then that user will get a high maxperip restriction of 10.

Negative matching
Most people would use only normal (positive) matching, such as eg. However, it also positive to do negative matches, such as:.

If you use negative matching then the rules are as follows:
 * If all your entries use negative matching then we match by default, such as with :
 * 192.168.1.1: not a match
 * 10.1.1.1: not a match
 * Anything else: match!
 * If you mix both positive and negative matches then we do not match by default, example: :
 * irc1.example.com: not a match
 * irc2.example.com: not a match
 * irc3.example.com: match!
 * anything else: not a match
