## How many subnets can a 48 site prefix support quizlet?

With a network prefix of 48, there will be 16 bits available for subnetting because the interface ID starts at bit 64. Sixteen bits will yield 65536 subnets.

## What does a 29 subnet mean?

/29 means 6 usable addresses: 196.44.198.32 – 196.44.198.39. Typically, 196.44. 198.33 would be your gateway.

## What does 24 mean in IP address?

The number after the slash represents the number of consecutive 1’s in the subnet mask. For example, 192.168.10.0/24 is equal to the network 192.168.10.0 with a 255.255.255.0 subnet mask. If you convert 255.255.255.0 to binary, you end up with 24 consecutive 1 ‘s: 11111111.11111111.11111111.00000000.

## What is a 255.255 254.0 subnet?

255.255.254.0 = 23 bits mask = 510 hosts (512 -2 ) 255.255.252.0 = 22 bits mask = 1022 hosts (1024 -2 ) 255.255.248.0 = 21 bits mask = 2046 hosts (2048 -2) You always multiply by 2 or divide by 2..and remove 2 hosts (broadcast and network)

## What does 28 mean in IP address?

It’s a subnet mask. IP address has 4 octets of 8 bits each and 32 bits in total. 28 means, first 28 bits denote network ID while 4 bits are used for hosts or they identify the hosts.

## What is a 32 subnet?

the /32 is the CIDR (shorthand) and refers to how many 1’s are in the subnet mask. For /32 that is 255.255.255.255 or 11111111.11111111.11111111.1111111. that means you can only have one ip address, on your network before needing a gateway/router to get outside that network. with /32 it’s just you.

## What does it mean 192.168 0.0 24?

1. 192.168.0.0 Refers to the IP adress /24 refers to the subnet. / 24 subnet is 255.255.255.0. 192.168.0.0/24 is common for home networks.

## Which of the following is the best definition of IP spoofing?

IP spoofing is the creation of Internet Protocol (IP) packets which have a modified source address in order to either hide the identity of the sender, to impersonate another computer system, or both.

## How many IP addresses are there?

4,294,967,296 IPv4 addressesThe two most common versions of IP in use today are Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). Both IPv4 and IPv6 addresses come from finite pools of numbers. For IPv4, this pool is 32-bits (232) in size and contains 4,294,967,296 IPv4 addresses.

## What does 30 mean in IP address?

Ipv4 is 32 bit address. Were /30 called subnet mask of network and it is known as class-less network, because your ip address is of class C and it default subnet mask is 255.255.255.0. while the /30 shows that your subnet reserve another 6 bit for network. 255.255.255.252. Or in binary.

## What are the benefits of subnetting?

5 Subnetting BenefitsImprove network performance and speed. A single broadcast packet sends out information that reaches every device connected to that network because each device has an entry point into the network. … Reduce network congestion. … Boost network security. … Control network growth. … Ease administration.

## How do you determine the number of IP addresses in a subnet?

Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.

## What does IP address 192.168 1.15 29 mean?

According to the question, the given IP address falls under the category of the class C network mask (192 to 223). Again, /29 subnet mask indicates that the network address can be divided into 8 subnets. Thus, it represents the broadcast address.

## What is Subnet IP?

A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. … This results in the logical division of an IP address into two fields: the network number or routing prefix and the rest field or host identifier.
