Networking

The networking I got outside of K3s stuff

Static IP Assignment

In my homelab, I require identical network behavior whether I’m at home, in the office, or on the road. To achieve this, I assign static IP addresses to my core devices on the 192.168.8.0/24 network:

Device	Role	IPv4 Address
Router	Default gateway	192.168.8.1
Switch	Layer-2 switch	192.168.8.2
RpiMaster	Compute node	192.168.8.5
RpiNode #1	Compute node	192.168.8.6
RpiNode #2	Compute node	192.168.8.7
RpiNode #3 (soon)	Compute node	192.168.8.8

This way, no matter where I plug in, I always reach the same IPs.

DNS Aliases for Service Access

To simplify access to management interfaces and services, I use a consistent domain namespace under da.lab. I add DNS host entries on my router that map sub-domains to the static IPs:

Alias	Target IP	Purpose
da.lab.router	192.168.8.1	Router UI
da.lab.switch	192.168.8.2	Switch UI

Router

This is what i see when i access da.lab.router.

Switch

This is what i see when i access da.lab.switch.
