Which ipv4 network class address contains a first octet in the range of 128 to 191?
class b
In IPv4 addressing an IP address whose first octet is in the range of 192-223 belongs to a class?
Class C
When using classful IPv4 addressing a network ID always ends with an octet of?
Always ends with an octet of 0
How is an IPv4 address normally written?
The normal format is dotted decimal, where each octet is converted from binary to decimal and separated by a period, thus: 192.168.100.123
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
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
Expressed in dotted-decimal format the IPv4 address range is what?
0.0.0.0 to 255.255.255.255
How big are the network and host ID fields for a Class A address?
A class A address is one of the IPv4 class-full networks. There are 3 of these class-full networks in IPv4; class (A, B, and C). The entire IPv4 address range is 32 bits long. The address range is broken up into 4 x (8 bits) referred to as octets, and then giving the whole 32 bit address range. The classes are defined as follows… Class A = reserve the first octet, or 8 bits for network addresses and leave the remaining three for host addresses. Reserving the addresses for the network is also referred to as the network mask. In other words do not assign any address in the reserved, first octet, to a host. Class A = 11111111.00000000.00000000.00000000 also known as a /8 bits reserved for net Class B = 11111111.11111111.00000000.00000000 also known as a /16 bits reserved for net Class C = 11111111.11111111.11111111.00000000 also known as a /24 bits reserved for net So the answer is; a class A network has an 8 bit field for the network, and a 24 bit field for the host
What are two characteristics of IPv4?
The first characteristic is that the IPv4 is completely connectionless. The second is that they are media independent and can be unreliable.
How many octets in ip address?
IPv4 addresses have 4 octets, each octet separated by a period. For example, at this time, one of Yahoo's servers has an ip address of 67.195.160.76.
What is the range for experimental addresses?
One major block of addresses reserved for special purposes is the IPv4 experimental address range 240.0.0.0 to 255.255.255.254. Currently, they cannot be used in IPv4 networks. However, these addresses could be used for research or experimentation.
An IP Address or IPV4 number is a set of four numbers each within what range?
0 to 255
