For public access? Many companies don't want to just for security 
paranoia, but that won't be so bad if someone has a DMZ.

Also define "well known"... not many companies could guarantee they won't 
change IP address in a year, never mind two or three! I guess the 
requirement is that they own the IP allocation outright themselves, rather 
than as part of their ISP (i.e. they could take the IP addresses with them 
if they changed ISP). I think the term is a "direct assignment".

Red Hat has one for example ( according to "whois 
66 dot 187 dot 229 dot 0 at whois dot arin dot net"). But of course I don't know of any public 
recursing servers in Red Hat.

But I thought of one other large company with one. And would you believe 
it, it's DNS server allows recursion! See below:

rift:~$ dig sources.redhat.com @ns.ascom.ch any

; <<>> DiG 9.2.1 <<>> sources.redhat.com @ns.ascom.ch any

So Andrew, do you think you could verify internally that ns.ascom.ch will 
be staying on its IP address and will continue not to require client 
recursion support as at present? :-) Ascom also appears to have a direct 
assignment from RIPE.

If not, it's a company with this type of address allocation we'd want to 
do it. And that isn't eCosCentric at least unfortunately.
