UK ISP Andrews & Arnold Trial DNS over HTTPS (DoH) and DoT

Broadband ISP Andrews & Arnold (AAISP) has today announced that they’ve started a trial of both DNS over HTTPS (DoH) and DNS over TLS (DoT) services, which encrypts Domain Name System requests (i.e. turning IP addresses into human readable domains like ISPreview.co.uk and back again) in order to make them secure.

Lately DoH has been in the news a lot, not least due to Firefox‘s (Mozilla) decision to enable the feature by default in their popular website browser (here). A number of major broadband ISPs are also deeply unhappy with this change as it would take DNS request away from their visibility and disrupt some of their systems (e.g. website filtering / parental controls, account management features, CDNs etc.).

Eventually ISPs will probably need to adopt DoH too and one of the first to setup its own servers is AAISP, which interestingly has also made them available for use by non-customers (details here).

AAISPs DoH/DoT Disclaimer

We are trialling a DNS over HTTPS (DoH) and DNS over TLS (DoT) proxy to our DNS services. If you want to encrypt your DNS lookups to our servers, you are welcome to use this, whether you are an A&A customer or not.

This is a free of charge service, and we may vary, suspend, or terminate it at any time, without notice. (In practice, as usual, we’ll try to give reasonable notice, via our status pages). We may also rate-limit or block IP addresses if the service is abused.

If you use this, it’s at your own risk, and we are not liable to you for any losses you may suffer as a result of using it.

Privacy-wise, we do not filter or log your lookups, but we do use server logs to maintain our systems and resolve problems. Here’s our privacy notice and, if you use this service, we’ll process your data as if you were a customer.
