Going to test this with the 4K stream of the England match on iplayer tonight, using Google DNS

I've just added google#s HTTPS settings, however if I browse to https://1.1.1.1/help it says that i'm not using DoH? It does recognise that I'm using google's service though...

I think that only recognises it's own (cloudflare) DoH

Tried some Sky go / BT sport, using virgins cache and it seems ok, iplayer appears to be getting sent to a cache with an ntl hostname which i'm still having issues with...

If anyone else wants to test the hostnames are vod-progressive.akamaized.net / vod-uhd-uk-live.akamaized.net which resolve to m163-mp1.cvx2-c.lng.dial.ntli.net / m202-mp1.cvx2-c.lng.dial.ntli.net respectively

Re: Virgin Akamai Cache Congestion

Bit of an update re iplayer..

I may be wrong here, but going off the hostnames it looks like some strange routing on virgin's end, going via new york?

Would explain the huge latency to that server too!

Does anyone else see the same strange routing / high latency on their VM connection?

--- 23.206.169.90 ping statistics ---
40 packets transmitted, 40 received, 0% packet loss, time 39051ms
rtt min/avg/max/mdev = 128.974/131.397/136.025/1.927 ms

EDIT:

These are examples of the hosts / IPs for the routes that seem to be broken on VM, not sure how we'd get anyone at VM to look into it though!

Live UHD - ve-uhd-push-uk-live.akamaized.net - 2.22.22.112
On demand HD - vod-dash-uk-live.akamaized.net (104.100.95.49)

Re: Virgin Akamai Cache Congestion

Cheers General, definitely looks like there's an issue with the routing there

Re: Virgin Akamai Cache Congestion

So bit of a follow up / conclusion if anyone is still following / comes across this from google.

tl;dr - akamai won't work properly when using cloudflare DNS with virgin (as of now), use Google's 8.8.8.8 resolver.

The reason for buffering with cloudflare is due to them not supporting ECS, basically this sends your subnet with the DNS packet so the resolver knows to send you to a local / ISP cache.

Google does support this, which is why issues are resolved using google DNS, and i assume virgin's DNS is set to send you to their own local cache anyway.

Re: Virgin Akamai Cache Congestion

So to sum up for everyone reading.................buy a proper router and use google's dns and you won't have to put up with any of this shit.

Sort of, if you're not using virgin's DNS, use Google / Quad9 / OpenDNS, just be aware you might run into issues using cloudflare

Finally sorted my issues with Adguard, I could set individual devices to my Synology box - but if I set my WAN DNS entried 1 and 2 so my NAS, I would lose internet connectivity. This same config with pihole worked.

What seems to fix it, is leave the DNS1/2 settings as either blank or normal Google resolver and change the "DNS Server" settings under the Asus LAN tab.

Now, rather than have just my router in the adguard device list, i pretty much have everything
