BT DNS Servers Dropping my Website

silklink — Thu, 14 Jul 2022 19:12:37 GMT

I have the BT Hub 6 and therefore have to use BT's DNS servers.

I have a website that I'm sure has suffered from spammy neighbours in the past couple of months (on the same IP block etc etc).

I'm not able to connect to my website - the domain is simply not known. Yet I can get to it via a mobile network or VPN / Proxy. So it's not my BT Hub (although I did try turning off the firewall) and I reckon this narrows it down to BT's DNS servers.

How do I get my website re-listed?

Thanks in advance

Assuming your web site is not anything illegal if you post the address on this thread forum user will be able to try and access it to see if it is in the unlikely event being blocked by BT or some other reason that you can not access it.

The website is silklink.co.uk

Unfortunately I am away from home at present and I am not using a BT connection so I am unable to say if it is working or not with BT, it is OK on my mobile, but I'm sure some of the other forum members will report back on this.

No problem here with BT DNS servers.

@silklink

Wouldn't work for me using Edge, so I switched to Opera. Still no joy so I activated Opera's free VPN and we're good to go. One of the technical experts will have to advise as I'm too old!

and with the VPN activated:

Thanks for checking. Yes I can connect with VPN. Also with mobile. As soon as I turn on WiFi on the phone in my home I can no longer access the site

This worked for me in Edge : SilkLink – Web and Business Development Services but I had to include https

Interesting that it has worked for 2 respondents in Edge. I personally hate Edge and anything to do with Microsoft and the Internet. However it makes you wonder where BT are

Works for me with Firefox, Opera, Chrome and Edge.

All without VPN

Maybe it's on some BT DNS servers but not all. It certainly isn't working for me on the BT network this morning.

Is there somewhere I can email to get this resolved?

Make sure you have web protect disabled to verify it isn't that rather than a DNS issue

Have you tried using NSLOOKUP ?

In windows create a comand prompt and type "nslookup" without the quotes - you should get a couple of lines of infomation and a ">" prompt. If you type silklink.co.uk you should get returned the ip address(es) for the website.

I notice that in the case of silklink.co.uk it is giving a private address (192.168.0.1) as well as the public address - that could be a setup problem with the DNS entry and cause problems if you use a 192.168.0.? subnet yourself.

By default nslookup will use the DNS server pointed to on your PC which is likely to be your BT router. If you want you can select another DNS server, I tried 8.8.8.8 (google's DNS server) but that returns the same as BTs DNS server but in the opposite order. I don't believe the problem is BT's DNS servers but rather the way our website address has been setup.

Hey CountryPaul, thanks

I think you are on to something there. I tried with one of my other hosted sites and, yes, I only see the one public IP for that one, but get what looks to be the same subnet IP for silklink.co.uk using Google's DNS servers

I've gone back to the hosting service support with these details. Hopefully, they can sort it out.

Thanks for your help

Just an update.

I got my website host provider to remove the private IP address that was set up in my custom domain settings for some reason (must have been recent because I've been able to access it prior to a few weeks ago)

So thanks all for your contributions and help
