Lost my Proxmox URL (alien.top)

[SOLVED]

This might be the dumbest thing to happen to me.

I've been running a home server for over a year now with Proxmox as my main OS and two VMs on it (Windows server 2019 & Ubuntu server). It has been a long time since I've needed to access Proxmox for anything and I recently lost all my browser history on Chrome.

It just occured to me that I should probably save my proxmox ip address but for the life of me I don't remember what it is. It is not in my browser history because that was recently reset.

I have access to both VMs so I'm hoping there's a way to find the proxmox IP address from them.

​

So far I have tried ip route on the Linux VM and ipconfig on the Windows VM. This is only getting me the ip of the VMs. Am I screwed or is there a way for me to get the Proxmox ip?

EDIT: Thank you to those who suggested the router logs. I recognized the IP there and was able to access it!

I know it has been answered with a better answers than what I am about to give, but I use Fing on my smartphone for stuff like this.

Having not used proxmox, I'm surprised that this is a problem that can even happen at all

Is there no official tool to help people with this? I usually do my self-hosting through my NAS and it has an official program to detect NAS from that brand on the LAN

Official tool? Oh, you mean some UPNP thingy that spews all over the network in an attempt to protect the end-users from having to think? Some people are allergic to that, y'know. I'm sorta middle of the road myself, it sure is handy sometimes, but I'm not the biggest fan. See https://nordvpn.com/blog/what-is-upnp/ for the tale of a non-fan.

Of course, there are other tools out there:

IPAM - properly record the layout of your network and all IP addresses in the first place

Wiki - generally document everything

network scanner (nmap or other) - for finding the devices that have snuck onto your network without being documented or those that have gone rogue

As for Proxmox Virtual Environment (PVE), though it is very popular in the self-hosted world, given the dual-licensing and the usability on a insanely wide range of hardware, Proxmox positions it as an enterprise product, and us enterprise network folks aren't much for UPNP.

Another alternative for next time. Scan the whole network with nmap for open port 8006, that should give you the up as well.

That made smile. Glad you found help here and solved your issue!

So... You are going to set up a small DNS-Server next too? ;-)
No really, I can recommend PiHole for DNS-AdBlock and it allows to set DNS entries too. That's why I use for my 2 Raspberries and the few VMs + network equipment.
