Making changes in the server room

This is an overview/checklist for what to do when you add hardware or make changes in the server room.

Add server

We keep our infra inventory in Netbox, which can be accessed by everyone who's part of the Github organization.

Link to contact list
A “Contact” holds information about how to get in touch with a specific contact person
Click “Add” in the top right to add a new
- Group: Nettlaug members
- Fill out real name, e-mail and phone number
We need accurate contact info for all personal devices in the server room. If someone needs to contact you (i.e in case of accidentally removed power, need to move your device or if it has an alarm), we need to be able to get in touch with you.
Important: do NOT add personal information about other members without their consent

Link to tenants list
A “Tenant” holds information about whom something (device, IP) is assigned to
Click “Add” in the top right to add a new
- Name: nick/handle (upper/lowercase as you want yourself)
- Slug: lowercase nick/handle
- Group: Nettlaug members
Add yourself as contact to the tenant
- Group: Nettlaug members
- Contact: <your contact>
- Role: Nettlaug member
- Priority: Primary

3.1 Public IPv4 (VLAN 130)

We have a limited number of public IPv4 addresses. You will find those in this list
The config for this network is:
- Network ID: 185.35.202.192/26
- First IP: 185.35.202.193
- Last IP: 185.35.202.254
- Gateway: 185.35.202.193
- Netmask: 255.255.255.192
Set “Nettlaug members” as tenant group, and your own tenant as tenant for the address
Fill out something descriptive (like hostname) in the Description field
Take note of the last octet if the IP (right-most group of numbers)

3.2 Public IPv6 (VLAN 130) - single address

Each host with a v4 address can bind a corresponding v6 address
You'll find the IPv6 addresses in this list
Pattern: 2a02:ed06::<IPv4 octet>
- Example: IPv4 address is 185.35.202.193, that makes the IPv6 address 2a02:ed06::193
The config for this network is:
- Network ID: 2a02:ed06::/64
- First usable IP: 20a2:ed06::1
- Last usable IP: 2a02:ed06::ffff:ffff:ffff:fffe
- Gateway: 20a2:ed06::1
- Netmask: ffff:ffff:ffff:ffff:0:0:0:0
Set Nettlaug members as tenant group, and your own tenant as tenant for the address
Fill out something descriptive (like hostname) in the Description field

3.3 Public IPv6 (VLAN 130) - multiple addresses

If you need more than one IPv6 address, you can assign a range of IPv6 addresses to yourself. This will not affect any routing, but just reserve those addresses in the inventory, so that we don't get collisions.
Add a prefix in this list and use the following parameters:
- Prefix: 2a02:ed06::N:0/112 (where N is the next available prefix)
  - N can anything you want between 0001 and ffff (not 0000)
- Status: Container
- Role: Nettlaug-member hosts
- Is a pool: -on-
- Mark utilized: -on-
- Scope type: DCIM > Site
- Site: Hausmania
- VLAN: NETT-SRV (130)
- Tenant group: Nettlaug members
- Tenant: <your tenant>

Make sure to add “Interface” components as well (use eth0, eth1, eth2 etc. if you don't have their numbering) for the device type. This will allow you to document where it's connected.
Interfaces etc. are only populated on a Device from the Device Type when it is initially created. When changing the Device Type after Device creation, you need to either manually move over changes or recreate the Device.
