What are the various classifications of ip address ranges in existence apart from Class A,B,C and D addressing. For instance what does the range 212.198.0.255-202.190.0.255 denote in specific?

There ranges are

Class   Leftmost bits   Start address   Finish address
A              0xxx     0.0.0.0     127.255.255.255
B              10xx     128.0.0.0   191.255.255.255
C              110x     192.0.0.0   223.255.255.255


D & E classes are also present but D class is only Reserved for Multicasting and E class is for Experimental; used for research

Class   Leftmost bits   Start address   Finish address

D              1110     224.0.0.0   239.255.255.255
E              1111     240.0.0.0   255.255.255.255

  • OK its my bad.You mean to say that How you can calculate the number of IPs between two ranges like How you can calculate Number of IPs between `212.198.0.255 - 202.190.0.255 ` – Freak Feb 26 '13 at 07:06
  • No not that, ip addr of few countries will be only be within a specific range . .in similar way is there any other classification . . – Madhu Feb 26 '13 at 10:46
