Help understanding options for network names (self.selfhosted)

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 haven't used proxmox but I can share with you my setup.

It also has several docker deployments plus some services running directly in the machines using a reverse proxy to only manage a couple of IPs given by tailscale.
So for pihole it was first manually configured with its tailsacle IP and included it in the DNS pointing to the machine which has the reverse proxy.
I'm using caddy, so the Caddyfile has this entry:

pihole.hosted.local {
  reverse_proxy <Tailscale IP>:<port>
}

You can have several blocks like this to manage your different services.
