That's a good spot. The DNS servers the HH5 using are serving the same address for goo.gl, feeds.feedburner.com, and quizlet.com. And they are all broekn.
|Broadband network IP address:||86.171.XXX.YYY|
Whilst I can change it, that'll break BT's parental controls (which is the only thing that keeps me with BT). As a parent, I can't sit with the kids every minute they're on the internet. I guess we can change it long enough for our youngest to be able to do his Spanish assignments on quizlet.com.
WRT to powering off and back again, the modem has a battery backup - disconnected it and the internet keeps chugging away. Unfortunately the front panel is not readily accessible otherwise I'd hit the reset switch. [ Behind enormous bookcase with solid back ].
So now we have BT serving bad DNS records for FTTP customers. All we need now is someone at BT to give a hoot.
Odd thing is though that those BT DNS servers give me the same answer as Google.
C:\Users\smf22>nslookup quizlet.com 188.8.131.52 Server: indnsc90.ukcore.bt.net Address: 184.108.40.206 Non-authoritative answer: Name: quizlet.com Addresses: 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 C:\Users\smf22>nslookup quizlet.com 184.108.40.206 Server: google-public-dns-a.google.com Address: 220.127.116.11 Non-authoritative answer: Name: quizlet.com Addresses: 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206
If you're able to change the DNS server on the client you could try different BT DNS servers so as not to break the parental controls. Here's some that I know of:
That's really interesting. If I flush DNS and use the same DNS server, the result is the broekn BT address:
> ipconfig /flushdns Windows IP Configuration Successfully flushed the DNS Resolver Cache. > nslookup quizlet.com 220.127.116.11 Server: indnsc90.ukcore.bt.net Address: 18.104.22.168 Non-authoritative answer: Name: quizlet.com Address: 22.214.171.124
I get the same result from the other BT DNS servers, eg
> nslookup quizlet.com 126.96.36.199 Server: indnsc41.ukcore.bt.net Address: 188.8.131.52 Non-authoritative answer: Name: quizlet.com Address: 184.108.40.206
> nslookup quizlet.com 220.127.116.11
There is a similar thread on plusnet with other addresses resolving to same BT address:
No real solution there bar switching to an external DNS server which is fine modulo breaking parental controls.
Anyone from BT want to comment on why your DNS has this issue?
Turning off parental controls "fixes" this issue, I tried it* and the broekn DNS behaviour goes away.
Parental controls turned on and the broekn resolutions are back.
BT, why does enabling parental controls result in bad DNS resolutions for common sites?
[ Only works from IE/Firefox, page goes into a loop with Chrome 54 ].
We have BT Parental Controls enabled on our HH5 and connectivity to the BT network over FTTP.
DNS responses to a number of popular services resolve to an unreachable address. It's always the same address: 18.104.22.168
Example services broken:
Turning off BT's Parental Control results in resolutions that are reachable on the public Internet.
There's a thread here on how we figured this out:
BT support , why are these resolutions broken? Thanks
Opened a thread in the BT Extras forum as this seems more appropropriate.
Thanks to jmf22 for help in getting this far.
In case it's not obvious, visiting these services produces nothing. No parental warning page, just an opening TCP handshake that never completes. Your parental controls breaks podcast serving from feedburner, Google URL shortener, and the site where my son is supposed to practise his Spanish for school.
FTR, manually adding the sites to the approved sites in parental controls enables them to resolve.
This cannot be WAI, black holing requests with no warning page?
