- Dylan16807 7y agoThat talks about whether you have servers on multiple networks. If it debunks the idea that you should have at least two servers I can't find where.
- cnst 7y agoWell, maybe because DJB takes it for granted that you don't actually need two servers in the first place, so, there's not much to debunk? % dig ns yp.to +short uz5jmyqz3gz2bhnuzg0rr0cml9u8pntyhn2jhtqn04yt3sm5h235c1.yp.to. % If your provider requires more than one server, just make something up, within reason, of course: % dig @tonic.to yp.to ns … ;; AUTHORITY SECTION: yp.to. 86400 IN NS uz5jmyqz3gz2bhnuzg0rr0cml9u8pntyhn2jhtqn04yt3sm5h235c1.ns.yp.to. yp.to. 86400 IN NS uz5jmyqz3gz2bhnuzg0rr0cml9u8pntyhn2jhtqn04yt3sm5h235c1.yp.to. ;; ADDITIONAL SECTION: uz5jmyqz3gz2bhnuzg0rr0cml9u8pntyhn2jhtqn04yt3sm5h235c1.yp.to. 86400 IN A 131.193.32.108 uz5jmyqz3gz2bhnuzg0rr0cml9u8pntyhn2jhtqn04yt3sm5h235c1.ns.yp.to. 86400 IN A 131.193.32.109
- Dylan16807 7y agoThe question is whether you're violating the standard or doing something unreasonable. Clearly DNS can't prevent you from using one server, just like it can't prevent you from using one network you own.
- Legogris 7y agoThese are some valid arguments against third-party providers. Assuming nobody's perfect, I still see benefit in having redundancy for cases of downtime. Could just be a duplicated setup on a separate physical network (if all your DNS records point to the same network your DNS is on, I guess it's pointless with network separation, but I don't think that is very common).
