How many IP addresses in one ip octet?

A complete IP address has 4 octets. MPGMichael We are talking IPv4 because IPv6 uses quintets. There are 4 octets in an IPv4 address. Each octet is separated by a dot (.) Each place has a binary value assigned to it as follows. 128s, 64s, 32s, 16s, 8s, 4, 2s, and 1s place The place values repeat in each octet The place values are read from right to left in binary numbers Within each octet there are 2^8 or 2 to the 8thpower possible addresses. So the math answer is 256. However if you write it out you will see that 128+64+32+16+8+4+2+1 = 255 and 256 is actually carried to the next octet. So there are 255 possible addresses in each octet For example a class C address would look like this 192.168.1.2 or binary 11000000.10101000.00000001.00000010


Convert the 32 bits binary ip address into dotted decimal notation100111000000000111100110000000111?

People often refer to the sections of a dotted decimal IP address as an octet for example, with the address 192.168.0.1, 192 is an octet, 168 is an octet, 0 is an octet and 1 is an octet. They call it this because each part of the IP address I just describes refers to 8 bits of the 32 bit IP address. Case and point: 192 = 11000000 168 = 10101000 0 = 00000000 1 = 00000001 To create the whole IP address in binary, I just put one after the other in the order they would appear in a IP address so 192.168.0.1 = 11000000101010000000000000000001. It's important to remember that every octet is 8 bits long hence why it's named an octet so, even though 0 in decimal is 0 in binary, in a IP address 0 in decimal is 00000000 in a IP address. Now that you understand how to convert a dotted decimal IP address into binary it should be clear how to change it back the other way around. Since your number is too long I am just gonna chop off the right most 1. Your first number, which is the left most 8 bits of the IP address is 10011100 which is 156 in decimal. We do this for each set of 8 bits afterwards so we would have: 10011100 = 156 00000001 = 1 11100110 = 230 00000011 = 4 This would create a final dotted decimal IP address of 156.1.230.1. Keep in mind your number is too long so I had to throw away a digit which means it may have been the wrong one and this isn't what the initial IP was supposed to be but now that you know the method you can re apply it to the proper binary IP address and see what the dotted decimal version is.


Subnet specifications classes?

The classes are based on what range the first octet of the ip address falls in. Class A: 0-127 Class B: 128-191 Class C: 192-223


Why are IP address classified into classes?

For classful addressing, the first octet identifies the class to which it belongs. There is also a way of looking at the first few bits of the first octet, but that makes it more difficult. For an IpV4 address, you have 4 octets for the IP address. Looking at the first octet, to determine the range, use the following: 1 - 126 class A 127 local loopback address 128 - 191 class B 192 - 223 class C 224 - 239 class D 240 - 254 class E
