How many bits can be used to create the host space?

How many bits is a host?

There are 16 host bits because, when you convert 255.255. 0.0 to binary, there are 16 binary 0s—the last 16 bits in the mask.

How many bits will be available to specify the host addresses?

As all IPv4 networks have 32 bits, and each “section” of the address denoted by the decimal points contains eight bits, “192.0. 2.0/24” leaves eight bits to contain host addresses. This is enough space for 256 host addresses.

How many bits should your borrow from host bits?

In this example: 192.10. 10.0 , we need to calculate 14 Networks, means we should have at least 4 Bits (All Ones) borrowed from the Host which means (N = 4) to provide the total Number of Networks. So , 2 = 16 ( 4 is the least number of bits can be borrowed to accomdate 14 Networks .

What is host bit?

Host bits are the portion of an IP address that identify a specific host in a subnet. The subnet mask determines how much of the address is used for network bits and host bits. For example, an IP (v4) address of 192.168. 0.64/26 has a 6-bit host portion, because 26 out of 32 bits are reserved for the network portion.

How many hosts can be addressed with 4 host bits?

A /28 CIDR notation indicates 4 bits are left for hosts (32 – 28 = 4). Using the 2n-2 formula, or 24 – 2, or 16 – 2, you see the answer is 14. In other words, /28 supports 14 hosts, which isn’t enough to meet the need of 24 addresses in the question.

How many bits of a Class A IP address are used for host information?

A class A network number uses the first eight bits of the IP address as its “network part.” The remaining 24 bits comprise the host part of the IP address, as illustrated in Figure 3-2 below.

How many host addresses are available?

Answers Explanation & Hints:

Subtracting the network and broadcast addresses leaves 62 usable host addresses.

How many bits are in the network part of the address and how many are in the host part of the address?

In a Class A network, the first eight bits, or the first dotted decimal, is the network part of the address, with the remaining part of the address being the host part of the address. There are 128 possible Class A networks.

How many subnet you can create if you borrow 7 bits from the host portion?

What’s the largest decimal number we can create with these 7 bits? 64 + 32 + 16 + 8 + 4 + 2 + 1 = 127. Don’t forget that we start counting at 0 so in total we have 128 addresses. Our original class C network has now been subnetted into two subnets that each have 128 addresses.

How many bits is the minimum I require for allocating addresses to these hosts?

So back to answer our initial question of the minimum subnet size to accommodate 20 hosts, the minimum number of host bits required is 5 bits (2^5 = 32). 4 bits (2^4 = 16) will be too small. So 5 bits used for the host IDs leaves us with 32 – 5 = 27 network bits.

What does IP range 0 24 mean?

0.0 Refers to the IP adress /24 refers to the subnet. / 24 subnet is 255.255. 255.0. … 0.0/24 is common for home networks.
