Migration from PlusNet to EE - nslookup timeout if server not specified

YorkshireMidge — Tue, 21 Jul 2026 21:07:08 GMT

Just been migrated from Plusnet to EE today, and everything went well but I just noticed something a bit odd when I came to do an nslookup from my desktop.

Basically, if the DNS servers weren't specified, the request would time out and you can see the address that pops up in the first nslookup is the IPv6 global unicast address.

The only difference I can see from my old PlusNet hub is IPv6 is disabled on that, and enabled on the EE one and it doesn't look like it can be changed.

You can see in the second example, I stipulate the default BT DNS address 81.139.56.100 used by my hub, and it then works. Ditto, if I specify the Google DNS server 8.8.8.8.

Hub is SH31B running r4.26.2-R-1923137-PROD-83002

Any ideas? Thanks.

@YorkshireMidge While your posted pics are being checked for general viewing can you double check your current FW that you have posted, here is what the latest others have posted....

FW: r4.26.3-R-1923144-PROD-83002 and the gui is at App version 3.14.5 12/06/2026 OP Posted

If your hub is just new OOB as today it may be the version you are quoting so still to FW update.

PN were only recently playing about getting iPv6 to work on there system EE has had it for years.

Don't worry, the images were awaiting approval. I have now done so & they should appear soon.

1st & 2nd NSLOOKUP results are about reversed between you.

@XRaySpeX Yes that would be correct, my router is already using the correct DNS resolver, and know idea what the IP the OP has posted if it is a DNS IP or the wan IP on the posting.

That's correct Jim - this is straight out the box which arrived a few days back. Presumably there is no way to force a firmware update to the latest version.

Thanks - hopefully my question will make more sense now!

@YorkshireMidge You are correct there is no forcing or finding for an EE box, they do it all, and with the way that the FW updates have been going lately it's maybe a good reason yours has not been touched when first connected. Linked the pinned posting for you. The latest may or may not be just the 100% correct another experienced user trying to work out if it's the FW updated latest or the app with the issue or just both, but sure looking like FW currently my opinion only.....

OK thanks Jim - at least I can work around it which is the main thing.

Just checked my hub and it seems to have updated itself and FW is now showing as r4.26.3-R-1923144-PROD-83002 but still seeing the same issue.

@YorkshireMidge It's worth doing the 5 minute power off reset to the EE Hub, then seeing what is going on when powered back up again from the fresh restart.

Issue resolved itself after a factory reset of the hub in connection with another fault I had (see https://community.ee.co.uk/t5/Broadband-Landline/Migration-from-PlusNet-to-EE-CCTV-port-forwarding-issue/td-p/1630271 ).

I now see nslookups resolved without any timeouts and without having to specify the DNS service.
