Accessing a locally hosted webserver

Instead of agonisingly typing out this:

http://127.0.0.1:3000

Try

http://0:3000

It might seem a little trivial, but I mean, come on! That's heaps of letters you're saving every day!

kane@192-168-1-5 ⮀ ~ ⮀ echo -n "localhost:3000"|wc      
   0       1      14
 kane@192-168-1-5 ⮀ ~ ⮀ echo -n "0:3000"|wc
 0       1       6
