While it's tempting to make fun of Qwest here, variations on this theme -
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 184.108.40.206
NS2.easydns.com. 29449 A 220.127.116.11
remote1.easydns.com. 29434 A 18.104.22.168
remote2.easydns.com. 29428 A 22.214.171.124
prolexic/Prime Communications Ltd. DONBEST (NET-209-200-131-0-1)

So, 4 ips, 3 ISP's 3 route objects... they seem to atleast follow some of
