Production Network
For the final DN42 separate, there are two main networks, the Management and the DN42 networks. The management network provides supporting services (mainly ROA) to the router, but does not expose them to the DN42 network. The management network also does not make use of DN42 address space.
The management network uses the address space 172.19.255.240/28, which precedes the address space used by DN42, 172.20.0.0/14.
| Hostname | Description | IP Address |
|---|---|---|
| - | Router | 172.19.255.241 |
roa-1 |
Primary RTR cache server | 172.19.255.242 |
roa-2 |
Fallback RTR cache server | 172.19.255.243 |
roa-srv |
ROA signature database generator | 172.19.255.244 |

Monitoring and alerts server | 172.19.255.245 |
The DN42 network is comprised of two separate networks, one providing services, and one used to access the network without using NAT. These networks uses the address space from AS4242421878, 172.23.119.64/27 and fde6:a552:874f::/48.
The services network uses 172.23.119.64/28 (the first half of the IPv4 allocation) and fde6:a552:874f:1c2d::/64. EUI-64 is used for predictable address generation based on router advertisements.
