What is the use of 0.0 0.0 IP address?

0.0 is used with a network mask of 0 to depict the default route as a destination subnet. This destination is expressed as “0.0. 0.0/0” in CIDR notation. It matches all addresses in the IPv4 address space and is present on most hosts, directed towards a local router.

What destination adress is 255.255 255.255 for?
