So I finally got connected to fibre today, and I was pleased to discover that the ISP (https://simplybroadband.co.nz/) offers IPv6 as well. Is this common nowadays? We all know about the public DNS services offered by Google (8.8.8.8, 8.8.4.4) and Cloudflare (1.1.1.1, 1.0.0.1); did you know these addresses have names as well? And of course there are IPv6 addresses to go with the IPv4 ones. Try this command to find out all the related Google DNS services: host -a dns.google. (Yup, that’s “dns.google.”, no “.com” or anything else on the end.) That’s quite a breathtaking list of entries. For Cloudflare, try host one.one.one.one. Note that the “-a” option (“tell me everything”) doesn’t work with Cloudflare; quite a few online services are now imposing restrictions on these “all info” lookups, but clearly not Google, at least not on this domain: obviously they want it to remain easy for people to discover the services they’re offering.
