Any clever ways to determine external ip of home router when away from home?

#1

Our home router's external ip had remained unchanged for long periods of time - typically a year or more until recently. In the last month it has already changed 3 times, so when I try to remotely connect I cannot until I find out what the latest external ip is.

Have some of you come up with any creative ways to get notified what the home router's external ip is when away from home. Is there a script that could be run - say once an hour - that could compare the current external ip to the last saved one and send a text or email with the new one when it's been changed?

It's called DyDNS.

Most consumer routers have DyDNS support or you can host your own DyDNS updater behind your firewall to update the public IP address with a hostname.

Plenty of free DyDNS services out there.

Also, it seems that routers nowadays provide access remotely through an account with the manufacturer.

At least, for me, this was the case previously with TP-Link, eero and now Nokia. I can log in to my account in the app and see all the network details, including the external IP address.

Does Channels DVR somehow report the server IP address, either in clients or in web interface when remote?

This is exactly what the Remote Streaming feature does. It maintains a dynamic dns to reach back to your house.

Check the domain you get redirected to after loading https://my.channelsdvr.net.

It did when I experimented with Cloudflare WARP and troubleshooting reported what the IP had been and what it was changed to by WARP, but it took a few hours to no longer show the redirect after I turned WARP back off. I removed WARP shortly after that.

It attempts to update every three hours or so, which of course can have an up three hour failure window, but in practice is actually fine.

We have years of people using it without complaints.

I assumed that's how remote streaming worked, but I didn't know there was a way to see the home router's external ip while the redirection is happening. I looked for it in the log and didn't see anything there.

Put Google Remote desktop on an always on PC at home and remote to it and get the External IP.

Or depending on your Home router, you may be able to remote to it via their app. I have Eero and I can use the app to connect to it.

It will be the URL the browser gets redirected to after you sign in.
https://X-X-X-X.############.u.channelsdvr.net/
Your external (Internet) IP will be shown as X-X-X-X

it's also listed under Settings, General, Remote Streaming .. next to Enable button it should show your external IP address

Problem is you can't see that when remote if you can't connect.
Another reason why I use Tailscale.

I ended up installing the Nighthawk App on my phone and I can use that to check on the External IP Address of the Internet Port for my home router.
