How many bits are assigned to the host portion of the address?
The first 64 bits are the network portion and the remaining 64 bits are the host portion of the address.
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 hosts can be on a subnet if you use 14 bits for hosts?
Class A
| Network Bits | Subnet Mask | Number of Hosts |
|---|---|---|
| /12 | 255.240.0.0 | 1048574 |
| /13 | 255.248.0.0 | 524286 |
| /14 | 255.252.0.0 | 262142 |
| /15 | 255.254.0.0 | 131070 |
How many bits is a MAC address?
48 bits
Historically, MAC addresses are 48 bits long. They have two halves: the first 24 bits form the Organizationally Unique Identifier (OUI) and the last 24 bits form a serial number (formally called an extension identifier).
How many bits of a Class A IP address are used for host information?
Class A addresses: The first 8 bits of the IP address are used for the network ID. The final 24 bits are used for the host ID. Class B addresses: The first 16 bits of the IP address are used for the network ID. The final 16 bits are for the host ID.
How many hosts are in a 25 subnet?

| Addresses | Hosts | |
|---|---|---|
| / 25 | 128 | 126 |
| / 24 | 256 | 254 |
| / 23 | 512 | 510 |
| / 22 | 1024 | 1022 |
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 addresses are in a 27 subnet?
Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References
| CIDR | Subnet mask | # of usable IP addresses |
|---|---|---|
| /28 | 255.255.255.240 | 14 |
| /27 | 255.255.255.224 | 30 |
| /26 | 255.255.255.192 | 62 |
| /25 | 255.255.255.128 | 126 |
How many hosts does a Class B address support?
65,534 hosts
Therefore, each Class B address can support up to 65,534 hosts.
How many bits are used to represent the host address of a computer?
The IP address is a 32-bit number that uniquely identifies a network interface on a machine. An IP address is typically written in decimal digits, formatted as four 8-bit fields separated by periods. Each 8-bit field represents a byte of the IP address.
How can an IP address class be determined whether it’s a class A B or C address?
If the address is written in decimal format, the first number determines the address. If the first number is between 0 and 127 inclusive, the address is class A. If the first number is between 128 and 191 inclusive, the address is class B. If the first number is between 192 and 223 inclusive, the address is class C.
What is the total no of bits for n w/id host for class an W?
We will take Class A as an example and analyse it so you can understand exactly what is happening here: Any Class A network has a total of 7 bits for the Network ID (bit 8 is always set to 0) and 24 bits for the Host ID.
How many bits are in an IPv6 address?
An IPv6 address is made up of how many bits? The subnet mask of an IP address does which of the following?. a. Provides encryption in a TCP/IP network
Which is network and host portions of an IP address D?
Defines network and host portions of an IP address d. Allows users to use a computer’s name rather than its address If a protocol is routable, which TCP/IP layer does it operate at? a. Network access
Do you need to assign static IP addresses to each computer?
There’s no need to assign static IP addresses to each computer. protocol? (Choose all that apply.) a. HTTP b. DNS d. FTP Which of the following is not found in a connectionless Transport-layer protocol?
