Help understanding options for network names (lemmy.world)

I am building up a selfhosted homelab after a few years of building up services on a single old desktop computer that I bought for $300. I had installed Ubuntu on it, and upgraded the RAM, etc and basically just used Docker to stand-up various services that all of you would be familiar with.

As I grew my use, it started to get more difficult to manage ports and networks and so I decided to make an investment and buy a used HP380 G8 server and installed proxmox. I love it.

The problem is now instead of a proliferation of ports now I have a proliferation of ips. Also, my damn Internet provider doesn't allow me to disable DHCP and its "reserve ip" is broken. It has an option for "bridge mode" which seems to allow me to make it simply a gateway but I haven't tried that mostly because I don't want to impact my family during the day/night when they are using the network.

What I have tried to setup various nameservers but they aren't doing what I want. I installed unbound yesterday to play around and it works but I don't know how to get the IP address/Name from proxmox over to the /etc/unbound.conf file for example.

My question is simply, what do you guys use to keep track of your IPs? Ideally, I could have something in Proxmox that registers the name/ip that I could patch into pihole or unbound or dnsmasq and fairly easily be able to manage that.

Any advice?

I use docker + traefik + a simple domain alias in my router to give all of my services easy to remember dns names.

Can you put your own router behind, what I presume, is the ISP router? Then you can manage DHCP and IP address reservation.

This turned out to be the solution that I chose. My internet provider did not support DHCP and even DNS was hard coded which made it hard for me. So, i switched the modem into Bridge mode and installed opnsense on a computer that I had after installing a 2x1GB NIC for it. Now I have full control over naming and now everything mostly works as I need it to.

That's awesome, glad you were able to find a solution!

Unbound is a recursive DNS, not an authorative. An authorative DNS server is needed for adding your own records. I suggest using bind, which can be both a recursive and an authorative.

I‘m not sure if I understand your problem. How many VMs, hostnames, etc. are we talking about?

[–] LordChaos82@fosstodon.org 1 points 2 years ago

@knaak I have an excel sheet with all the IP addresses in my homelab.

This is very unlikely, but does your ISP router offer any dynamic DNS options with the DHCP?
The process would be DHCP giving out address --> Host registered, returns Hostname --> DHCP gets hostname --> DDNS update sent to DNS server
