Another Clarification needed

Kikode

Hello guys,
Well as you may guess I have rescheduled my test for this Monday because I needed a little more time to cram. So I'm still hacking away at the material. Can someone clarify If I understand this correctly? For some reason the books are confusing me.


10.0.0.0-10.255.255.255 are the Private Class A IP addresses right?

well If I get a question like this on a test and it asked me what class it is is it more of a Private class then a Class A? Cause the practice test said I was wrong when I put Class A it said it's considered a Private Class. Hope you can understand my meaning


One other quick question.

Bridge: Connects same access protocols.
Gateway: Connects Different protocols.
Routers: Connects Different Network types.

Is that correct? My books seem to flip flop these duties around a bit just want to make sure I'm understanding that correctly. Any help would be awesome thanks.

P.S. Cross your fingers for me

That is correct, a class A address is any address where the first bit is 0. The range is 1.x.x.x-127.x.x.x. 10.x.x.x is considered private, along with two other ranges:

10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

It is correct that 10.x.x.x is a class A, it is more correct to call it a private class A address.

Bridges break up collision domains, they are layer-2 devices and make forward/filter decisions based on MAC addresses.

Gateways enable communication outside the local network and are typically routers.

Routers work at layers 2&3 and break up broadcast domains. They can use the same protocol(Ethernet) on all interfaces or different ones on each interface. Routers are used to connect networks that could not otherwise be connected as well(such as Ethernet & Token Ring, or Ethernet & ATM/Frame Relay).

Good luck.
