How many valid host addresses are available on an IPv4 subnet that is configured with a 26 mask 62?
12. How many valid host addresses are available on an IPv4 subnet that is configured with a /26 mask? When a /26 mask is used, 6 bits are used as host bits. With 6 bits, 64 addresses are possible, but one address is for the subnet number and one address is for a broadcast.
How many valid host addresses are available on an IPv4 subnet that is configured with a slash 28 mask?
Explanation: A /28 mask is the same as 255.255. 255.240. This leaves 4 host bits. With 4 host bits, 16 IP addresses are possible, but one address represents the subnet number and one address represents the broadcast address.
What does 8 mean in IP address?
The “8” denotes that there are 24 bits left over in the network to contain IPv4 host addresses: 16,777,216 addresses to be exact.

How many valid host addresses are available on an IPv4 subnet 26?

How many valid host addresses are available?
With 6 bits, 64 addresses are possible, but one address is for the subnet number and one address is for a broadcast. This leaves 62 addresses that can be assigned to network devices.
How many host addresses are available in the 128 network?
The first octet of a Class B address offers 64 possibilities, 128 to 191. The second octet has 256 possibilities, 0 to 255. That yields 16,384 addresses, or 25 percent of the total IP space.
How many hosts are in a subnet?

How many host addresses can the following network IP and subnet mask support 192.168 1.0 24?
So, a machine that has an IP address that is 192.168. 1.200 /24 would be in the same subnet. And because the subnet mask is /24, that means that the entire last octet can be used to define host machine – 28 = 256 – 2 = 254 usable addresses.
How many IPv4 addresses are left?
There are only about 4.3 billion possible IPv4 addresses, which engineers assumed would be more than enough in the 1990s. With IPv6, there are about 340 trillion trillion trillion combinations — specifically: 340,282,366,920,938,463,463,374,607,431,768,211,456. (Let’s just say 340 gajillion.)
What is a 255.255 255.0 subnet?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
What is IPv4 address?
The IPv4 address is a 32-bit number that uniquely identifies a network interface on a machine. An IPv4 address is typically written in decimal digits, formatted as four 8-bit fields that are separated by periods. Each 8-bit field represents a byte of the IPv4 address.
What is 26 subnet mask?
A subnet mask of 255.255. 255.192 is 11111111.11111111. 11111111.11000000 in binary, or 26 ones, hence /26.
What is a 31 used for?
31-bit Subnet Mask (/31)
A 31-bit subnet mask is often used for an interface that is the endpoint of a point-to-point network. The use of 31-bit subnet masks for IPv4 point-to-point links is described in RFC 3021.
What is a slash 24 subnet?
/24 indicates a subnet mask of 255.255. 255.0, or in binary octets. 11111111.11111111.11111111.00000000. A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host address.
