Bugzilla automated email settings file

Several months ago I've successfully installed bugzilla on local test server. Now, I wanted to change my credentials email in bugzilla and I've got following email: > Bugzilla has received a request to change the email address for the > account user@test.com to your address. > > To confirm the change, visit the following link: > > http://84.21.236.183/bugzilla/token.cgi?t=8aiQF72AFE&a=cfmem > > If you are not the person who made this request, or you wish to cancel > this request, visit the following link: > > http://84.21.236.183/bugzilla/token.cgi?t=8aiQF72AFE&a=cxlem > > If you do nothing, the request will lapse after 3 days (on October 10, > 2015 at 15:46 CEST). The problem is, that I've moved server to new location and got new internet provider, which gave me new static IP address, so 84.21.236.183 is no longer valid. Where do I setup this IP in bugzilla settings files so it will point to new IP address?
