Could anyone answer these technical computer related questions???


Daniel Rossi

Hi could anyone help me with these questions??:

IP Addresses - Classes
Class A - Supports 16 million hosts on each of 127 networks
Class B - Supports 65,000 hosts on each of 16,000 networks
Class C - Supports 254 hosts on each of 2 million networks

What i would like to know is there ranges like for example 192.168 etc is a class c i think etc

and another question if someone could answer please is this:

What does a router do that a switch doesnt??

If anyone could help me out here i would really appreciate that :)

for private lans, the IPs and can be used if that is what you are askin

still help plz

thanks Roban for ur help on the router question but Geffy like for example this is what i mean to say:

Class A: between ip address to ip address
Class B: between ip address to ip address
Class C: between ip address to ip address

if u get my drift hehe ;)


Assumming an IP address is represented as a.b.c.d, where

a is between 1 and 126 = Class A = Range is a.b.c.d
a is between 128 and 191 = Class B = Range is
a is between 192 and 223 = Class C = Range is

As Enyo said, there are special ranges for private use, e.g.

I believe there are class D and E but I have never come across them.

thanks bob the builder and Enyo there is class D and E but they are reserverd for "future use"

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there
