With Path MTU Discovery (which is on by default), you effectively
create a distict route for every host.  Currently, routes appear to
take ~20 minutes to expire.  It seems perfectly reasonable for a big
FTP or WWW server to see 50,000 different hosts in this period.  This
is getting fairly close to the 64K possible entries.

IPV6 gives you a bigger worst case, but shouldn't affect the typical
behaviour.

Why is there such resistance to moving from a short to an int?
