In case of TCP/IP problems like lost of connectivity, network troubles, router problems, etc... It is always useful to know if there is something wrong with local and public addresses.
I wrote a small VB Script which gives informations on the computer ip, server ip and public ip.
I wonder if it works for everybody, especially for those having problems, therefore a feedback is very welcome.

Unzip, run and wait few seconds.

Then over here we are out of range

A lot of
In fact the main routers used in France are what we call "ISP_NAME_BOX"
All the ISP give their own router and therefore manage their firmware through updates, etc... The default gateway address could be 192.168.1.1 or 192.168.0.1 or 10.0.0.0.1 or class b, etc....
I have 2 ISPs one adsl (20000kb/s) which address is 192.168.1.1 and one fiber (120000kb/s) which is 10.0.0.0.1
My daughter has 172.16.1.0 if i remember well
We can change eventually the gateway address (with my isp anyway)

Yet another cool script from Sidney1st

You should make a tutorial so "new" users can figure out how to use and upload it to the forums for us, that would save lots of time

It is the most common here, the main ISP (Orange) using it on their routers.

Yep but even on small network we can use any of the ip of the A, B, C classes, again depending of our ISP or on some cases, like mine, we can use any of those reserved by ICANN.

Class A: up to 16.777.214 computers
0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Network Computers

Class B: up to 65.534 computers
10xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Network Computers


Class C: up to 254 computers
110xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Network Computers



ICANN reserved the following.

• Private IP class A : 10.0.0.1 to 10.255.255.254, very big networks.
• Private IP class B : 172.16.0.1 to 172.31.255.254, average size networks
• Private IP class C : 192.168.0.1 à 192.168.0.254, for small private networks.

ISPs use all of them here for their routers

NB: It is not to expalin to you, but it could be useful for newbies to know about how it works.
