We use DNS... Its been around about as long as IPv4
- azinman2 7y agoDNS doesn’t help when you’re having to manually enter an IP into a config, which is what the OP implied.
- oarsinsync 7y agoIf an application supports IPv6, it should support DNS. If it doesn’t support DNS, that feels like a bug. The only configuration item that should require manual entry of an IPv6 address is a NIC. Even that has other mechanisms. Everything else should support DNS. Edit: doh, the second place is the dns zone file
- Paperweight 7y agoSo you gotta log into your registrar and copy paste your IPv6 address and wait god knows how long for it to propagate...
- oarsinsync 7y agoOr you can host your own dns. Or you can get a decent dns host. It doesn’t need to be your domain registrar, much like you don’t need your website or email hosted with your domain registrar.
- icebraining 7y agoDNS doesn't actually "propagate", all you're waiting for is the caches to expire, and you can control that by keeping a low TTL on the record.
- azinman2 7y agoAgain, to me the OP is talking explicitly about places where you have to enter it in. What are the other mechanisms? Let’s forget about situations where you can copy/paste or use DHCP. My answer would be to use my phone to take a photo of the address (if not easily accessible via web browser), and then use that to manually enter it. Probably not a situation where you can rely on memory, unfortunately.
- oarsinsync 7y agoOutside of the NIC and DNS, where else do you need to enter in an IP literal?
- zenexer 7y agoFirewalls, for example. We have huge files containing risk levels for various IP addresses. Most of it is automated, but sometimes we have to tweak something manually. These aren't IP addresses that we control, so DNS isn't helpful. Often we're dealing with ranges as well, for which DNS is also unhelpful.
- dredmorbius 7y agoTechnically, you could claim you're authoritative, just hope the assignments don't leak ;-)

- ay 7y agoMy experience is contrary: Put the “interesting” addresses in DNS immediately upon acquiring/configuring them. When you need a literal - lookup DNS name, copy-paste from one terminal into the other. I do this for both Ipv4 and Ipv6 addresses. Turns out the human brain sometimes does also have difficulty figuring the differences between 192.168.129.1 and 192.186.130.1 when one of them is mistyped....
- penagwin 7y agoYou still need to put that ip address manually into a few places to have that setup (dns, static ip settings, possibly router settings, etc.)
- snagglegaggle 7y agoYeah, but what about ephemeral DNS for your LAN? Zeroconf and NetBIOS work but can be harder to set up than IPv4 (especially if your install media doesn't have it set up by default).
- api 7y agoThis isn't a great solution. Every IT person knows "its always DNS," and you have to set up IP stuff to bring up DNS in general. DNS is brittle and doesn't deal well with multiple network domains or debugging if the network is down, and those are precisely the situations where one finds oneself typing IPs. I really think the size of the IPs is a major cause of slow V6 uptake.
- Fnoord 7y agoSize in which regard though? They're hexadecimals. If they were numbers or letters (0-9, a-z instead of 0-0, a-f) the number of bits would be still high, but with lower amount of characters. You might loose something beautiful as autoconfig but who needs a /64 for one device anyway? Plus, it does not work well for anonymity. You might as well randomize it.
