does 127.0.0.1 have a default subnet mask?


I know its loopback, and i know 127.x.x.x cannot be subnetted.... but is there a default subnet?

 

255.255.255.0

 

no.

 

I would just assume 255.255.255.0 but I'm not certain.. Why?

 

Oh, try 255.0.0.0

 

255.0.0.0

 

255.255.255.0 is the default for a class C

Class A - 1.x.x.x - 126.x.x.x has a default of 255.0.0.0
Class B - 128.x.x.x - 191.x.x.x has a deafult of 255.255.0.0
Class C - 192.x.x.x - 223.x.x.x has a default of 255.255.255.0

I dont remember if 127 falls in A, B or neither.... and my textbook is pretty vague about it.

ET phone 127.0.0.1!!

 

yea i just found the same page :uhhok:

thanks guys

 

127.0.0.1 = 127.231.214.15 = 127.12.18.99 = 127.185.131.2

127.x.x.x all is loopback. The whole class A is a loopback.

Since it's a class A..... 255.0.0.0
