On Dns - Events - mIRC
< mirc‎ | on events

The ON DNS event triggers when a /dns command query either succeeds or fails, including when a user does not exist on the server.


ON <level>:DNS:<commands>


  • <level> - The corresponding access levels for the event to trigger.
  • <commands> - The commands to be performed when the event listener's criteria is met.

local identifiers


This identifier can be used to return all the address found.

$iaddress $naddress $raddress

These return to the ip address, host address, and resolved address, respectively. Although these identifiers work now, it is strongly advised that migration to using the $dns is made.


If /dns was performed on a nickname rather than an address, then $nick is filled with that nickname. Otherwise, $nick is filled with your own name.


Echo to the active window the results of the DNS:

ON *:DNS:echo -a $iif($1,$iif($dns(1).nick,$v1 has been resolved to) Hostmask: $dns(1).addr IP: $dns(1).ip,Could not resolve DNS query.)

The above example makes use of multiple $iif to ensure that we get proper results, without unforeseen issues. The first surrounding $iif checks to make sure any data has been returned. If no data is returned, then the /dns obviously failed; therefore, we have it return a statement which says that a resolution could not be made. If data has been returned, the second $iif checks to see if a .nick value can be extracted from the $dns. This is filled if a nickname was the target of the /dns request. If the nickname is filled, return the portion containing the nickname. If, however, the nickname is not present, only return the hostmask and ip address.
