HUBS: Gigabit copper between oxygen and the HUBS router in our rack.

Summerhall: Gigabit fibre between switch-g11-d and the Summerhall server room. This was originally intended to be connected directly to oxygen, but the SFP was incorrectly configured so we are currently using a VLAN via our switch.

Internal IPv4 10.38.32.0/20.

Routing is handled by oxygen, a Dell PowerEdge R610 running RouterOS.

185.34.62.0/26 and 2a04:5d00:70::/48 provided by HUBS.

Router address: 185.34.62.1
External NAT address: 185.34.62.2

This service will be ceased from 1st July 2020. The IPv4 addresses will continue to be routed via a tunnel until 14th July 2020.

Router IP: 46.226.0.133/31
Gateway IP: 46.226.0.132
