How could a hijacked DNS entry harm you?
You can leverage the trust in DNSSEC to distribute TLS and SSH fingerprints too, look up DANE.
Oh, now I see. I guess then the DNS64 server needs to do the dnssec verification on behalf of the user, then drop the RRSIG records for the v4->v6 translated names.
Oh, and now I realize I confused the direction. DNS64 makes v4 into v6.
I’m fortunate to get native IPv6, so I’m not very familiar, tho I think I have basic understanding.
Did you mean you need to pick just one of {authoritative DNS server, DNS64} to listen on port 53? No, because the authoritative DNS only needs to be accessible from the outside. Run it on another machine or nonstandard port, then expose via port forwarding. Machines in LAN don’t need direct access to the authoritative DNS server, they can just as well resolve via the regular system.
Are you sure you need DYNDNS? My ‘dynamic’ IP address changes so rarely that I just update my DNS entries manually when it does.
Could you elaborate on the “non-spying” bit? There’s not much they can infer from people looking up your IP. Unless you run their daemon that updates the IP, as opposed to curl in cron.
I just self-host my own DNS server. Works like a charm. Setting up DNSSEC was a tad fiddly tho.
Long story short:
dig can use a specific server)
An official Microsoft Linux distro has existed for a while now: https://en.m.wikipedia.org/wiki/Azure_Linux
There’s more Linux than Windwoes VMs in Azure, I hear.
I’m not sure if I agree.
Unless you own a CA, or are a powerful country able to coerce a CA, or mandate installing one into users’ PCs.
As for SSH - you missed the “TOFU” bit, Trust On First Use. Do you verify your SSH host keys every time before connecting to a new server? The docs for GitHub doesn’t even mention it.
I partially agree - encryption appears to be a solved problem today. Key distribution, however is not, it’s layers upon layers of half-solutions of wishful thinking, glued together with hope.
Depends on your threat model and priorities, right :) HPKP is helpful and does not require DNSSEC. DANE and CAA are helpful but require DNSSEC.
