I wasn't thinking of it as a problem, but rather as a possible solution.
If DNS labels happened to have a length restriction of less than 32, then
an IPv6 address represented as 32 hex digits would be distinguishable
from a DNS label by the fact that it was longer than a legal DNS label.

Unfortunately, the length limit on DNS labels turns out to be greater
than 32.
