I do agree the management issue with DNS are far harder, and here longer TTL are a double edged sword. But it is hard to design a system where the mistakes don't propagate to every DNS server, although some of the common tools do make it easier to check things are okay before updates are unleased.
What's interesting to me, atleast, is that this is about the 5th time someone has said similar things in the last 6 months: "DNS is harder than I thought it was" (or something along that line...)
So, do most folks think: 1) get domain-name 2) get 2 machines for DNS servers 3) put ips in TLD system and roll!
It seems like maybe that is all too common. Are the 'best practices' documented for Authoritative DNS somewhere central? Are they just not well publicized? Do registrars offer this information for end-users/clients? Do they show how their hosted solutions are better/works/in-compliance-with these best practices? (worldnic comes to mind)
Should this perhaps be better documented and presented at a future NANOG meeting? (and thus placed online in presentation format)

IETF tech transfer failure... see RFC 2870 (mislabled as root-server) for TLD zone machine best practices from several years ago... for even older guidelines ... RFC 1219.
Perhaps this falls under: "better documented" or "easy to find" or "not publicized" ? I'd be interested to see how many DNS hosting providers actually follow these themselves. Take EasyDNS for example (since they are on my mind, due to their GOOD service actually): easydns.com. 3600 NS ns1.easydns.com. easydns.com. 3600 NS ns2.easydns.com. easydns.com. 3600 NS remote1.easydns.com. easydns.com. 3600 NS remote2.easydns.com. NS1.easydns.com. 3600 A 216.220.40.243 NS2.easydns.com. 29449 A 209.200.151.4 remote1.easydns.com. 29434 A 209.200.131.4 remote2.easydns.com. 29428 A 205.210.42.20 CIDR: 205.210.42.0/24 NetName: SHMOOZE-NET prolexic/Prime Communications Ltd. DONBEST (NET-209-200-131-0-1) 209.200.131.0 - 209.200.131.255 NetRange: 216.220.32.0 - 216.220.63.255 CIDR: 216.220.32.0/19 NetName: Q9-NET1 NetRange: 209.200.128.0 - 209.200.191.255 CIDR: 209.200.128.0/18 NetName: PROLEXIC So, 4 ips, 3 ISP's 3 route objects... they seem to atleast follow some of the requirements. -Chris
