Re: Fwd: The Root has got an A record
Joe Blanchard wrote:
Hmm, B has the same one, and C has all the other Roots listedIts not records like
a.public-root.net. 369 IN A 220.127.116.11
that are the issue. That's as it should be. (Well... if you accept that public-root should be. ;-) )
This record, however, is not correct:
. 172800 IN A 18.104.22.168
That is the root.
For those of you who need reminding on how DNS works...
. the root
/ | \
/ | \
/ | \
.com .net .org top level domains
yahoo bgp4 domain names
www sea host (or subdomain)
The trailing dot is left out in day to day use when we use URLS like www.yahoo.com - however, its really www.yahoo.com. - note the dot on the end. That's the root.
Having an A record for the root is one better than having an A record for, say, .edu. In other words, this shouldn't work:
[aura.sea.bgp4.net] (ciscogeek) nslookup . a.public-root.net
As for what issues it could cause, I'm not sure. I can't think of any off hand, but who knows what poorly written application may not be expecting an A record for the root.
For most people though, it doesn't matter, because they aren't using public-root in the first place.
I now return you to the Cogent/Level3 thread.
