This question came from our site for system and network administrators. is the "any ip". It'll match anything basically. That's why in a routing table the default gateway is usually given as ip.of.default.gateway – Sirex Feb 17 '11 at 9:29

There is one default gateway and you pass through default gateway to reach hosts that are not in your subnet.

when you set route for some default gateway, and print that route it will show that connections to are made via IP of default gateway , meaning connecting anywhere outside own subnet is made via that IP.

Other situation where you can use is when you want to bind some service to listen on all interfaces (multiple public private ips, multiple NICs)
