Uses of Reverse DNS. The use of the network by individuals at Bath assumes and implies compliance with these policies without exception.
Understanding IP, DNS, and NetBIOS Tracking and Scan by Hostname
Every maintainer of hosts on the network has a duty to ensure they practise appropriate and proper use and must understand their responsibilities in this regard. Certain areas of IP allocation and naming will be delegated to named local supporters.
A list of the relevant delegated members will be published with the central data. Only authorised users of the University computer systems are entitled to use bath hostnames and IP addresses on the network.
Reverse domain name notation - Wikipedia
All hosts connected to the network must have a registered IP address and hostname. Hosts that are not registered will be given 24 hours to register after which their LAN access will be terminated. Registration of hosts is through lanmaster bath.
The technical background to IP-address allocation and hostname conventions is provided for information. A link between each range and its recognised IT supporters will be made.mouthtguarthono.cf

All hosts should have a unique name that is registered in the hosts DNS; the unique name will be registered so that reverse lookups are self consistent. For efficiency and fairness naming has been codified. In general, for end hosts, these take the form dcgi-name where "dc"is a 2-character department code,"gi" is a generic identifier and "-name" is a string which ensures uniqueness and does not violate RFC , or superseding RFC's.
