auto voice problem

[theskid]

hi im on a channel and depend on auto voice
and invite
i message the bots and they invite me the bots must check my address line
at first its ok
ribbit@soandso.com (this is a example)

and i get invite to other channel and auto voice

but after a few hours or so

invision or something changes my address line to
I18467R41C@soandso.com

as you can see rabbit@ has changed to I18467R41C@
and i dont get voiced or invited i usually have to restart my pc for it to go back to its original state tried everything the connection options still say what they originally did were does this I18467R41C@ come from

is this my user id

how do i prevent this from changing

There is no way for you or Invision to change the ident after you connected to a server.
Perhaps the network is doing something.
IRCops can change idents of people connected.
Check with the admins of the network.
