in numeric mode, the default route is printed as "default" rather than 0.0.0.0/0 or ::/0
From the man page:
"-n: Show network addresses and ports as numbers.
Normally netstat attempts to resolve addresses and ports, and display them symbolically.
if the -n option is specified, the address is printed numerically, according to the address family.
For more information regarding the Internet IPv4 ``dot format'', refer to inet(3).
Unspecified, or `wildcard'', addresses and ports appear as `*''."
