How to get periodically public IP address to Email?

essie · May 13, 2025

I need occasionally RDP to access my other computer from home but public IP changes quite often.
And RDP fails.

Is there any ready trick to get twice per day public IP to Email?

Any other suggested solution?

Opening RDP over the internet is a really bad idea, but you'd either want to setup a Dynamic DNS service or if you have a system always running at home you write a simple script to query any number of websites, get your public IP and send the email.

A better solution would be to setup a VPN service on your home network, connect to that and then RDP to the local device IP

Is it only E-Mail that is the question? I have Browser access to the E-Mail account provided by my ISP and can access from any computer with Internet service. If desired I could set up an installed E-Mail Client such as Thunderbird or SeaMonkey to manage from one computer. The ISPs in my area can provide a static IP address but there's an additional monthly cost.

TeamViewer (free) can be set up to automatically accept inbound connections in a secure way, as long as you can access it initially.
I have it set up on some friends' and family's computers to help them with technical problems.

I have used Teamviewer earlier but the lisence is too expensive €70 per month. Teamvierer free version doesn't work as company is paranoid about customers using it for work. I got continuosly blocked or sessions were limited to 30 seconds, when I attempted to help some friend or relative to fix Windows or Gmail problems. I have used TeamViewer perhaps 1-2 month. I have tired of asking and waiting Teamviewer support to reopen my account. Possibly they monitor traffic for Outlook usage, as 90% I open Emails in remote PC due to double verification of many popular sites.
probably they consider that someone wants to read Emails at work. It's just my guess. There is also Anydesk, but after Teamviewer I don't trust it too much.

@essie
Are you trying to access your work computer from home and you want it to automatically send you its public IP address? I think you really ought to discuss this with your employer!

If you work from home they should offer a solution.

Hi Kepler, I'm the employer you suggest to contact. Please check my initial message.
I had an idea to use senders IP address in automatically sent Email header to get public IP daily.
But I'm sure there are better and well tested solutions.
Just to get public IP using DDNS means dependency of 3rd party.

You never made clear that you were self-employed. Anyway, what email do you use? And are you running an email server at work, because if so, the IP address in the email header might not be what you are looking for.

To find the sender's IP address in an email header, follow these steps:

Step-by-Step Instructions:
Open the full email header
This varies by email client:

Gmail: Click the three dots (⋮) > Show original

Outlook: File > Properties > Internet headers

Thunderbird: More > View Source

Search for the first "Received:" line (from the bottom up)
Email headers list the path the message took from the sender to you. The bottom-most Received: line is usually the one added by the first mail server — closest to the sender.

Look for an IP address in square brackets
Example:

Received: from somehost.example.com (somehost.example.com. [203.0.113.42])
In this case, 203.0.113.42 is likely the sender's IP.

Remember, an IP6 address could look like this 2001:0db8:85a3:0000:0000:8a2e:0370:7334

Powershell:

(Invoke-WebRequest -Uri 'https://api.ipify.org?format=json' | ConvertFrom-Json).ip

Should get you your public IP address in a PowerShell script. Then you just need to work out how to get the information to yourself.

Will that still work if she uses Outlook?

Use a cloud storage service like OneDrive, Google Drive or Dropbox to share the file. The disadvantage of e-mail is you'll be receiving a set of messages that may need to be deleted after a while. Most cloud services only take a few seconds to sync a tiny text file.

You could create a scheduled task to run this command once an hour.

Code:

powershell -C "(Invoke-WebRequest -Uri 'https://api.ipify.org?format=json' | ConvertFrom-Json).ip | Out-File C:\Users\pseymour\OneDrive\Documents\MyPublicIP.txt -Force"

Pay your ISP to allocate a Static IP address to your home internet.
Or, what router do you use at home? Some routers allow you to setup DDNS. There are free DDNS services you can use.
Its been a while but I used to use it way back when WOL was much easier to manage.

In the U.S., static IP's normally require a business-tier contract from your ISP and the pricing is absurd.

My ISP in Australia, you get a free Static IP with a business plan, home accounts can get one for AU$5 a month (current exchange = US$3.20 per month)
Best ISP and connection I’ve ever had.

Yep, for Verizon it would cost me more than my Internet/TV/Phone contract just to add a static IP address!
