[Collisions] Weird dest IP addr

[Kevin White]

OK...I found some old hints files too, the problem is, I don't know if I
should trust them.  Anyone could fake one.  :)

I'll see if I can get an official list from IANA.

Yes, I noticed that 198.41.0.10 was the old j-root address.  198.41.0.11
seems to have been an old k-root as well.

Thanks,

Kevin

That is the case today.

Yup. 5 seconds with google found this old hints file:

;       This file holds the information on root name servers needed to
;       initialize cache of Internet domain name servers
	...
;       last update:    Aug 22, 1997
;       related version of root zone:   1997082200
	...

; temporarily housed at NSI (InterNIC)
;
.                        3600000      NS    J.ROOT-SERVERS.NET.
J.ROOT-SERVERS.NET.      3600000      A     198.41.0.10

The IP addresses of the root servers have changed from time to time and as
Warren says, the old addresses continue to get traffic because heaps of
deployed stuff never gets updated or knows any better.

Someone from IANA should be able to provide a list of when these addresses
changed.

My guess is Verisign still has/had its current root server answering queries
on the legacy addresses so things would still work for those who expected
the old address to remain active long after it had been retired.
