What is used to specify which bits of an ipv4 address are used for the network identifier and which bits are used for the host identifier?
Subnet Mask
How do you know which bits are host bit in a subnet mask?
Since a subnet mask is used to separate the network id from the host id, any 1 bits indicate the network portion and the 0 bits indicate host portion. As an example, in the subnet mask: 255.255.0.0 This indicates the first two octets are used for the network, and the last two octets (ipV4) are used for host portion of an address.
How do you know how many bits represent the network portion and the host portion?
When we express an IPv4 network address, we add a prefix length to the network address. The prefix length is the number of bits in the address that gives us the network portion. For example, in 172.16.4.0 /24, the /24 is the prefix length - it tells us that the first 24 bits are the network address. This leaves the remaining 8 bits, the last octet, as the host portion.
How many host bits in an IP address of 192.168.254.192?
IPv4 has 32-bits classified into 4 bytes out of which each byte is divided into network or hosts. Thus, it can have any combination like 1 host, 3 networks or 2 host, 2networks etc.
What is the length in bits of a logical IP address IPv4 and IPv6?
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
Within a classful addressing subnet mask the bits indicate that corresponding bits in an IPv4 address contain network information?
the 1 bits
How many networks are there in class a network?
There are a total of 126 networks with 16,777,214 addresses per network in a Class A Address of ipv4. Such a big range Ha!
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
How many address in IPv4 address?
32 bits in a IPv4 address
The Class B IPv4 address network ID is located in the?
The first 16 bits is the location of the Class B IPv4 address network ID based in classful addressing. 16 bit is an expression used for microcomputers with 16-bit microprocessors.
How do you determine what bits to use to calculate the network address?
An IP address comes in two formats: ipV4 and ipV6. In IpV4 32 bits are allocated to the IP address. In IpV6, 128 bits are allocated to the address. This is done by the protocol and is a standard for developing an IP address.
Which network class can support the most hosts?
The classful network A provides 16,777,216, the most available in classful networks.Unfortunately a class A network only allows for 256 possible networks.This is of course IPv4 stuffRemember the entire IPv4 address space is 32 bits wideIn class A the network mask is 255.0.0.0 meaning that the first octet or eight spaces are reserved for networks and the remaining 24 bits are available for host.OK so the number of host are 2^24 or 16,777,216 English 16 million 777 thousand and 216 hostsAnd don't forget all networks and subnets require reserving the first and last address for the network and the broadcast address.
