# Total IPV4 Address Range are :- 0.0.0.0 to 255.255.255.255

IP Address Classes :- When divide IP into a Categories. Total IP Addressing Scheme is divided into 5 classes.
# Class A IP Address
# Class B IP Address
# Class C IP Address
# Class D IP Address
# Class E IP Address

Class A, B and C Use in LAN and WAN.
Class D Multi-casting Class. 
E Research & Development.

IP Address Priority Bit Concept :- To identify the range of each class a bit called priority bit is used. Priority bit is the left most bits in the first Octet.
Class A Priority bit is 0
Class B Priority bit is 10
Class C Priority bit is 110
Class D Priority bit is 1110
Class E Priority bit is 1111

Class A Range of IP Address :- For class A range first bit of the first octet should be reserved for the priority bit.
00000000 = 0
00000001 = 1
to
01111111 = 127
0.0.0.0 to 127.255.255.255

0.X.X.X.X and 127.X.X.X these IP are reserved for network.

Class B Range of IP Address :- For class B range first two bit of the first octet should be reserved for the priority bit.
10000000 = 128
10000001 = 129
to 
10111111 = 191
128.0.0.0 to 191.255.255.255

Class C Range of IP Address :- For class C range first three bit of the first octet should be reserved for the priority bit.
11000000 = 192
11000001 = 193
to 
11011111 = 223
192.0.0.0 to 223.255.255.255

Class D Range of IP Address :- For class D range first four bit of the first octet should be reserved for the priority bit.
11100000 = 224
11100001 = 225
to 
11101111 = 239
224.0.0.0 to 239.255.255.255

Class E Range of IP Address :- For class E range first four bit of the first octet should be reserved for the priority bit.
11110000 = 240
11110001 = 241
to 
11111111 = 255
240.0.0.0 to 255.255.255.255

All Classes IP Addresses Range :-
