= New network =
Due to the complexity of our current network, I propose a redesign. Goal of this redesign is to simplify the network, by migrating all subnets into a single large subnet of sufficient size. By doing this, we can remove the dependency on the gateway for intra-vlan traffic.
== Proposal ==
We renumber everything into 10.208.42.0/23 (10.208.42.0 .. 10.208.43.255).
== How ==
We pick a day, get a bunch of people together on-site, and we renumber everything. Starting from the gateway, and working our way through *all* systems.
== Dependencies ==
- VPN prefix lists and firewalls need to be changed.
{{Outdated}}
= Space network =
The ports for this network are 25-48 on [[nurds-sw-01]]??
== DHCP ==
Runs on [[NURDServices]]
=== Settings ===
Router for the network is [[nurds-rtr-03]] its config you can find in [[librenms]]
=== Change requests ===
For changes in the network routing/nat for example:
* Portforwards
* Switchports
Please contact [[User:Zarya]]
==== Static ====
Request a ip from https://ipam.nurd.space/
==== DHCP ====
* Range: 10.208.42.2-10.208.43.254
* Netmask: 255.255.252.0
* Gateway: 10.208.42.1
* Domain: dhcp.nurd.space

= Student network =
'''obsolete but might still be in some configs'''
This network is separate from the space network. The DHCP runs on routerboard ([[nurds-rtr-03]]). The ports for this network are 1-24 on both the [[nurds-sw-01]] and [[nurds-sw-02]] switch.

Layer 2 overview

Below you can find the structure of the network as of 10-04-2022. Fat lines are LACP trunks Layer 2 overview 10-04-2022.svg

Layer 3 overview

we have a single-vlan flat network. Due to legacy, three different prefixes live on this vlan:

  • 10.208.11.0/24 (gateway 10.208.11.1)
  • 10.208.30.0/24 (gateway 10.208.30.1)
  • 10.208.42.0/23 (gateway 10.208.42.1)

IP addresses

10.208.30.0/24 is used for static allocations. Register your ip's in IPAM. 10.208.42.0/23 is used for dynamic allocations using DHCP

DNS

search nurd.space lan.nurd.space vm.nurd.space management.nurd.space router.nurd.space dhcp.nurd.space
nameserver 10.208.30.254

Layer 3 simplification

In order to reduce the unnescecary roundtips via the edgerouter, we need to flatten the networks into a single prefix. The proposal for this is to move to 10.208.28.0/22. This prefix would be used as fol lows (With the gateway living on 10.208.30.1):

  • 10.208.28.1 .. 10.208.29.255 DHCP
  • 10.208.30.1 .. 10.208.30.255 Static clients
  • 10.208.31.0 .. 10.208.30.254 reserved

Management URLs
