No. See http://www.ietf.org/rfc/rfc810.txt
"ASSUMPTIONS
1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
to 24 characters drawn from the alphabet (A-Z), digits (0-9), and the
minus sign (-) and period (.).=20
..."
This defined a policy that was imposed by "The NIC" of the time. I =
believe the policy was relaxed somewhat after the DNS protocol was =
specified which allowed domain names to be longer than the NIC's policy, =
and the resulting confusion necessitated the clarification in 2181.
