1384333 - FIrefox will give "server not found" on "o2.box" url (router access, O2=ISP)

Status: RESOLVED INVALID

(Core :: Networking: DNS, defect)

Description

[Dan]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0
Build ID: 20170628075643

Steps to reproduce:

enter "o2.box" in adress bar if you have an o2 homebox (2) router.


Actual results:

"Server not found"


Expected results:

the same should appear what appears when I enter "192.168.2.1" or so (default IP adress). This worked fine in last year's Firefox release, not working anymore since a few builds already.

If possible, could you try to capture the HTTP log when you enter "o2.box" in URL bar?

enabled all of the following modules:

timestamp,sync,nsHttp:5,nsSocketTransport:5,nsStreamPump:5,nsHostResolver:5)

Ahaaaa issue is caused by using either Google DNS in IPv4 (8.8.8.8, 8.8.4.4) or because of IPv6... (working when not using Google DNS) Can it be fixed in Firefox?

I will close this bug now.

If you want to request this new feature to firefox, fell free to file another bug.
We can discuss more details there. :)

I would call it a bug. Why won't you? Isn't that URL supposed to work, no matter which DNS I use?

No. Because o2.box is not a public domain, which means google's DNS server will never resolve o2.box to "192.168.2.1".
