  The SIP container is trying to comapre hostnames. To get the
  hostnames a reverse DNS lookup is performed.

• A new custom property was intorduced that allows you to
  disable the reverse DNS lookup.
  To disable reverse DNS lookups you should do the following:
  1. Enter the administrative console
  2. go to Application servers > server1 > SIP container >
  Custom properties
  3. add new custom property:
  name: ipauthenticator.check.host.name
  value: false
  4. press on the save button
