IP Reserved for Internal Usage?

Answered Question
Jul 5th, 2010

Perhaps I'm missing something obvious, but what does the following LAN setting in a Router do/refer to?

"IP Reserved for Internal Usage:"


Thanks,

From network administration point of view, the wireless access point is integrated with the router, which runs on IP address 192.168.1.1 by default. The reserved IP address, i.e. 192.168.1.2 by default, should not be used by anyone except for the WRVS4400N router itself. This is due to the way the router and access point were developed and integrated historically.

The internal IP address is resevred for the integrated access point inside the WRVS4400N.

Hi Malcolm,


Networking address space for the IP protocol is broken into classes — A, B, and C. (There is also Class D for multicasting and Class E for a small set of very reserved,“don't ever touch these” addresses.) In each of the Class A and Class C spaces, there are address ranges reserved for internal, non-Internet use (or a non-Internet routing space for IP traffic). There are two ranges in the Class A space: the 10.0.0.0 to 10.255.255.255 range (also represented as 10.x.x.x) and the 172.0.0.0 to 172.255.255.255 range (172.x.x.x) You may be using one of these spaces in your networks for internal addresses assigned to various hosts (network devices).


Hope to Help !!

Hi Ganesh, Thanks for the reply and the overview of classes/subnetting.  I've uploaded as screen shot in my reply to another reponse I received, as this setting seems to be on a more granular level than you addressed.  I realize my initial question perhaps wasn't clear enough as to the context of the router menus.

Malcolm, could you post a screenshot so we know what the context is?

Does this mean the "access point" (I'm assuming the wireless - with upto 4 SSIDs) is viewed as its own "device" on the network (ie. seperate from the router itself)?
