I'm not sure what you're asking.
If you want to learn about ip address's or just determining if someone in particular (router ip or private ip) specify on exactly what you want to learn in detail ???

Anyway... Routers IP are usually in Class C network ranges

192.0.0.0. TO 223.255.255.255

b.g. 192.168.0.1

''192.168.0.'' would be the Network ID and ''1'' would be identified as the Host ID

What exactly in networking do you want to know ?

Actually, there are four ranges of addresses that are private network addresses, however 223.x.x.x is not one of them.

10.0.0.0 – 10.255.255.255, single class A, 256 contiguous class B's
172.16.0.0 – 172.31.255.255, 16 contiguous class B's
192.168.0.0 – 192.168.255.255, single class B, 256 contiguous class C's
169.254.0.0 - 169.254.255.255, APIPA address range, single class C

There are several other IANA reserved private IP addresses ranges, thought they're NOT supposed to be used for private networks, the 1.0.0.0 - 2.255.255.255 range is one.

Well class A, B ,C are usually reserved to identify work stations routers, switches, and other devices.

Class A: 1.0.0.0 to 127.255.255.255
Class B: 128.0.0.0 to 191.255.255.255
Class C: 192.0.0.0. TO 223.255.255.255
Class D: 224.0.0.0 to 239.255.255.255
Class E: 240.0.0.0 to 255.255.255.255

D, and E are reserved for other use.

I'm still not sure exactly of (his) exact question.

Actually, there are no restrictions as to where you use a Class A, B, or C network as far as the first octet of the address is concerned. There are general recommendations as to the class of networks that might be employed using the various private address ranges, but it's not any sort of requirement.

See RFC 1918 which defines IANA Address Allocations.
