I wrote a networking test program that connects to my machine within the address range of 127.0.0.0/8.

The program keeps locking up.

I guess I am just hangin' with my homies...

This stemmed from me asking the question. If 127.0.0.1 is loopback, what is 127.0.0.2?

Isn't the entire 127.0.0.1/8 range a loop back?

@C0D4

Yes: 127.0.0.0/8 is the entire range.

The fun thing is that you can - thx to the large range - generate an entire network for fun under OSes like linux.

A good work for eg. interns learning network stuff.

Just generate network aliases on loopback and have fun with Wireshark.

I think since 2.4 ish the amount of network aliases is near unlimited, so you can do a whole lot of fun.

Great for testing firewalls and stuff.
