Layer 3

External IPv4: 185.34.62.0/26 provided by HUBS.

Internal IPv4: 10.38.32.0/20, with an external NAT address of 185.34.62.2.

IPv6: 2a04:5d00:70::/48 provided by HUBS.

Routing is currently handled by a Mikrotik RouterBOARD 450G.

Future

In future, routing will be handled by VMs on Oxygen, both running BSDRP.

At this point we will be splitting the responsibilities of the old Mikrotik 450G into two - One VM (Nickel) to handle our edge (BGP speaking + Public IP Space Gateway), and one (Iron) to handle NAT and act as a gateway for all internal space. PF will be handling NAT + Firewalling on these machines.

Record Keeping

NetBox - for VLANs, IPs, hardware and port locations (for some switches)
Edinburgh Hacklab Assigned Numbers Authority (EHANA) - port locations (for some switches)
