1. DNS (Domain Name System)

1.1. Caching Resolvers

Server name: resolver0.dns.ox.ac.uk resolver1.dns.ox.ac.uk resolver2.dns.ox.ac.uk
Server IP number: 129.67.1.1 129.67.1.180 163.1.2.1
Port number: 53 (TCP/UDP)
Status: Official

These resolvers should be used by all client systems across the university network. Each client should use at least two for redundancy (preferably not resolver0 and resolver1 together, as these are on the same subnet), and there is little reason not to list all three where possible.

1.2. Authoritative nameservers

Server name: auth0.dns.ox.ac.uk auth1.dns.ox.ac.uk auth2.dns.ox.ac.uk
Server IP number: 129.67.1.190 129.67.1.191 163.1.2.190
Port number: 53 (TCP/UDP)
Status: Official

If you require zone transfers to a departmental slave server, please contact hostmaster to arrange for access and for your server to receive NOTIFY messages upon updates.
