That's better, except that "pre-standard" isn't exactly accurate: port 1812
was specified in RFC 2058 but it was discovered after the fact that the port
was already assigned to the datametrics service (thus the new allocation);
furthermore, RADIUS Accounting has _never_ been a standard.  I would
suggest:

OLD:
Note that this doesn't account for a server using the commonly deployed
pre-standard UDP ports of 1812 and 1813.

NEW:
Note that this doesn't account for a server using the original UDP ports of
1812 and 1813.

...

Hope this helps.
