Known toplevel domains (summary)
Jem Taylor
a few weeks ago and one Mark Horton mailed to me; if you posted or mailed
any other additions i'm afraid they must have been caught by our disk
disaster a few weeks back - we lost mail and missed two weeks news ]
[ Mark, thanks for your mail; I'm afraid I can't answer your questions yet ]
Just to recap on the problem:
In view of the recent debate about the wisdom (or otherwise) of naming a system
as uk.......com , which introduces Little/Big-Endian ambiguity, I have collected
together the names of all the top-level domains of which I am aware. Since it
is desirable to avoid using any of the names in the list below as the final
component (or indeed any component) of a name, I am circulating this list and
would like to hear of any additions.
I would like to suggest that a new constraint be placed on new names, to the
effect that top-level names not be used as lower-level (especially final)
components of new registrations.
The reasons for this constraint are two-fold:
(1) Not permitting a top-level domain name to occur as the final sub-domain
name eliminates Little/Big End Ambiguity.
(2) Not permitting a top-level domain name to occur as an intermediate sub-
domain name allows users to input partially resolved domain names of the
form mydept.mysite instead of the fully-qualified domain name
mydept.mysite.subdom.top without thereby introducing Little/Big Ambiguity.
Examples of the Ambiguity:
(1) uk......com - or is that com.....uk ?
(2) uk.ac.edu.vax - typed as edu.vax from uk.ac.edu.prime - is that vax.edu ?
Although many sites stick firmly to one ordering or the other (JANET or ARPA),
some sites will always have to try to understand both orders, in order to
relay between incompatible domains or to allow users to type the addresses
which their correspondants have told them in the other order.
PLEASE consider the implications, and don't create ambiguous-order names !
-Jem Taylor.
