Has anyone seen anything like this ???
Jan 12 04:18:19 dnsmasq[341]: Insecure DS reply received for TD4A66J62GQ0MAI1GBPG6P7JSMOJI3KH.co.uk, could be bad domain configuration or lack of DNSSEC support from upstream DNS servers
Did you enable DNSSEC on your router? Reading that it just looks like the router is letting you know it wasn’t able to validate that particular domain name. Sometimes domain owners don’t setup their domain records correctly, and you cannot fix that.
I would not be concerned.
