Windows environment variables

Question

_{Tuesday, August 4, 2015 11:20 PM}

I set no proxy for the IP addresses 169.254.169.254 and 127.0.0.1.

The two IP addresses are separated by a ";", is it correct?

If I have a script that uses "http://169.254.169.254", because I have an environment variable 169.254.169.254. Will the script bypass proxy for http://169.254.169.254?

Hi,

I would agree with Bill, and no_proxy this variable should contain a comma-separated list of domain extensions proxy should not be used for. For instance, if the value of no_proxy is ‘.mit.edu’, proxy will not be used to retrieve documents from MIT.

You could check the below article for some reference regarding the set environment variables :

Hope it helps.

Best Regards,

Elaine

  I am not surprised. They are both non-routable addresses. 169.254 addresses are APIPA addresses. Look it up on the Internet it you don't know what they are. 127.0.0.1 is a loopback address. To the networking protocols it effectively means " this packet has reached its destination. Do not send it anywhere".

What's the correct syntax for multiple IP addresses. Looks like "169.254.169.254; 127.0.0.1" doesnt work but a single IP address 169.254.169.254  works

Hi

For some reason no_proxy system environment variable doesnt allow me to set more than one IP address.

It is ok to setx /m no_proxy "169.254.169.254"

but not setx /m no_proxy "169.254.169.254;127.0.0.1"

How do I include more than one IP addresses?
