The purpose of the Dynamic Host Configuration Protocol (DHCP) service is that when a computer is attached to a particular network, it may enquire particular details of its environment, and be supplied with a temporary IP address from a special pool. This meets two needs: as portable computers roam between different networks their IP addresses need to change accordingly, preferably without the need for user intervention; as the number of hosts connected to the Internet continues to grow, there is developing a shortage of available IP addresses.
2.2 Operator cover is provided from 08:30 to 20:30 on weekdays. Periodic monitoring takes place outside these hours, and informal arrangements exist for staff to be called, but no funding is provided to make this contractual.
2.3 If a fault is notified between 09:00 and 17:00 on a working day, OUCS will commence investigation and correction within one hour (provided that no similar fault is also being handled by the same team).
- Notification of faults, outages, etc is circulated on the mailing list firstname.lastname@example.org
Faults should be reported to email@example.com. OUCS will liaise with department and college computing officers: no end-user support is provided.
3.1 The requirements for University systems to make use of these services are given at http://www.oucs.ox.ac.uk/network/dhcp/. A department or college that wishes to join the scheme must surrender a pool of IP addresses from its own network allocation to be used for DHCP. All addresses in the pool must be registered in the DNS.
