	DNS service was terminated because it didn't work well (some problem with additional work needing to be done for some nameservers to accept delegating authority to us), nobody used it and it caused a potential security problem (which could have been fixed, but removing it was easier for the preceding reasons).

			Those DNS servers are also recursive for machines located on the University network.
