310053 - Excluding IP range in 'No Proxy for' does not work

Status: VERIFIED INVALID

(Core :: Networking, defect)

Description

[Peter Jetson]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915

Specifying an IP range such as 192.168.0.0/255 in the 'No Proxy for" field does
not work - IP's in that range are still forwarded to the defined proxy server.

Specifying individual IP's such as 192.168.0.104 and/or 192.168.0.254 does
exclude those IP's from the defined proxy server.


Reproducible: Always

Steps to Reproduce:
1. Define a manual proxy server.
2. Enter 192.168.0.0/255 in the 'No Proxy For' field.

Actual Results:  
IP's in the specified range are still forwarded to the defined proxy server.

Expected Results:  
IP's in the specified range should not have been forwarded to the defined proxy
server.

You need to enter 192.168/16 for that you want. Does that work?

the syntax is "192.168.0."

Sorry, I meant "192.168.0.0/16". See bug 80918 for the implementation. The other
private ip adress ranges are 10.0.0.0/8 and 172.16.0.0/12.

This does not work for me (Mozilla 1.7.12), see above.

huh, ok... clearly I misremembered.

however, it seems to me like what the reporter wants is 192.168.1.0/24, not /16.

Could be, I used http://en.wikipedia.org/wiki/Private_IP_address for the private
range.

Thank you, 192.168.0.0/24 works!  I didn't understand the syntax, and nothing I
read explained it.

Now that I've checked the wikipedia link that [e-mail] provided, it
appears that the /24 excludes 192.x.x.x - what I was really after was just
192.168.0.x, which is only 8 bits.  Although /8 is not shown as being valid on
that wikipedia link, I've just tried it (192.168.0.0/8) and it appears to work.

I am not sure what status to change this report to - FIXED doesn't seem
accurate, is INVALID the best status? 

Thanks, Peter

No, you want /24. /8 would match 192.x.x.x. It's the number of network bits.

the German link shows it better
http://de.wikipedia.org/wiki/Private_IP-Adresse

V/invalid (reported problem was config problem, not code problem).

we actually have docs on this on the mozilla site at:
/quality/networking/docs/aboutno_proxy_for.html

but maybe I didn't do the greatest job of linking it.
