| This utility allows for WAN IP
extraction and publication of dynamic IP changes that are typical of
most broadband-based connections. |

Wan2Web is a IP publishing app. It runs as a SysTray utility that queries
a external site for your WAN IP address (The address everyone on the Internet
sees you as). It then publishes this information to a FTP site that you
predefine to a file name that you can also define.
The one requirement here is that you must have a FTP server (or website that
supports FTP transfers) to publish the information to. As I have this
website, this is where I publish my IP address to. You will need to get
your own.
It's Windows-based, open source (GNU),
and solely written, maintained, hosted, and supported by me, Sean Shrum. Source code is written with
AutoIT (.au3) and the
most recent version can be found via the source link in the navbar above. If you're just looking for the latest binary build, it can be downloaded from
the binary link in the navbar above.
WAN2WEB really came about when I wanted to
VNC into my home PC from
work but every time I got to work, my home WAN IP would change (being behind a
dynamic broadband connection). I had no way of knowing what the new IP was.
Working with web servers a bit, I knew that I could pull the WAN IP of a visitor
with REMOTE_ADDR. I wrote a small script (included with the distribution)
called remote_addr.php.
This script returns back only the IP address of the remote visitor...their
current WAN IP. The resultant page back contains something like this:
I really got going on this project after DynDNS (one of the DDNS services
that most routers give you the option of using) decided to constantly email
account deletion notification to any account that didn't do any updates within
30 days. Unless your ISP changes your IP address daily/weekly, chances are
the only time your IP will change is if you unplug/reboot your modem...I'm one
of those people.
In order to get around the issue, I set up this tool to get my WAN IP by
going to http://www.shrum.net/remote_addr.php
that I then publish to my website to a filename that only I know. Whenever
I want to log into my home PC I look at that file on my site and my home
connection current IP address is right there.
Simply launch Wan2Web. First time runs will display 7 prompt and save your
responses for future use (except for password). You will be prompted for the following
information:
- [W]AN
...the site that you want to pull your WAN IP from (defaults to my
remote_addr.php, you can use any other site as long as the only value
returned is the WAN IP address)
- [S]erver
...the address to the FTP site to post updates to
- [U]sername
...the FTP username to use to log into the ftp server with
- [P]assword
...the password to log into the server (must be input if app is launched
directly versus via a commandline with all the parameters passed)
- [F]ilename
...the path/filename to store the updated info to
- [M]inutes
...how often to check for IP changes (defaults to 30)
- [V]erbose
...toggle bubbletips on/off
Wan2Web does not store passwords and you'll be required to input your FTP
account password every time Wan2Web is launched. This is just a security
precaution. If you really want to, you can either call the utility from
the command line and include the password in the call or mod the script to
include it like this
wan2web.exe w=http://www.shrum.net/remote_addr.php
s=ftp.shrum.net u=foo p=bar f=public_html/homeip.txt m=60 v=y
Or you can add a "Password" string key to the registry under HKCU\software\shrum.net\wan2web.
Whenever a IP change is detected, Wan2Web will generate 2 files. [filename].txt
and [filename].html. the .txt file will include the WAN IP address "@" and the
time of the post like this:
76.170.192.233 @ 2025/11/12 23:28:57
The .html file will be a redirect page that will point to the WAN IP address
that you can call when remote.
