Actually it is the same story with TLS 1.3 and TLS 1.2. A bunch of sites still doesn’t support TLS 1.3 (e. g. arstechnica.com, startpage.com) and some of them only support TLS 1.2 with RSA (e. g. startpage.com).
You can try this yourself in Firefox by disabling ciphers (search for security.ssl3
in about:config
) or by setting the minimum TLS version to 1.3 (security.tls.version.min
= 4
in about:config
).
Some domain providers (e. g. Strato) have dynamic DNS included. You can then use ddclient or, like in my case, your residential gateway and point them to the dynamic DNS servers of your domain provider.
Other providers (e. g. Netcup) have an API that allows modifying the A record of your domain. You can then use a third-party program or script to update the A record via the API.
