Quick Answer: How Many Subnets Can A 48 Site Prefix Support Quizlet?

How many subnets can a 48 site prefix support?

65,536 /64 subnetsLarge customers get a /48 prefix.

That gives them 65,536 /64 subnets..

How do you calculate subnets?

The number of subnets is found by counting the number of bits by which the initial mask was extended, also known as the subnet bits. Our initial address allocation was 192.168. 0.0 with a mask of 255.255. 0.0.

What is the slash after an IP address?

The slash following the IP address is the abbreviation for the subnet mask. … The amount of ones in the subnet mask is equal to the number of the abbreviation. For example, the /16 subnet mask you asked about would have 16 ones in a row, the rest of the numbers being zeros. 11111111.11111111.

What is the subnet mask for 192.168 1.0 24?

255.255.255.01.0 with subnet mask = 255.255. 255.0. Shorthand (AKA CIDR, Classless Inter-Domain Routing), this can be written 192.168. 1.0 /24 where the ‘/24’ represents the number of subnetwork bits active in the mask.

What is the maximum number of subnets?

Maximum number of subnets = 2^6-2 =62. Note that 2 is subtracted from 2^6. The RFC 950 specification reserves the subnet values consisting of all zeros (see above) and all ones (broadcast), reducing the number of available subnets by two. Maximum number of hosts is 2^10-2 = 1022.

What does IP address 192.168 1.15 29 mean?

Explanation: A broadcast address is the last address of any given network. This address cannot be assigned to a host, and it is used to communicate with all hosts on that network.

What does the IP address 172.17. 4.250/24 represent? Explanation: The /24 shows that the network address is 172.17.

What is IP subnetting?

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.

How many subnets are in a 24?

Deducting 248 from 256 gives us 8 so the subnets are 0, 8, 16, 24, 32, 40, 48… 240,248. 192.168….2-3 Subnetting.Dotted Decimal ValueCIDR notation255.255.255.0/24255.255.255.128/25255.255.255.192/26255.255.255.224/2719 more rows•Dec 12, 2013

How do you calculate the number of subnets?

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 are two benefits of subnetting networks?

But subnetting enables you to ensure that information remains in the subnetted network or broadcast domain, which allows other subnets to maximize their speed and effectiveness. Subnetting also divides your network’s broadcast domains, enabling you to better control traffic flow, thus increasing network performance!

How many 60 networks can be assigned from a 48 network address prefix?

64 – 48 = 16, and 216 is 65536, so there are 65536 /64 subnets in a /48 network, How many /64 networks are there in a /60? Again, deduct the size of the network from the size of the subnet. 64 – 60 = 4, and 24 is 16, so there are 16 /64 subnets in a /60.

What is a 64 subnet?

So a /64 indicates that the first 64 bits of the 128-bit IPv6 address are fixed. … There are several common prefix lengths for IPv6. A /64 is the size of a single LAN. As a customer you often get a /56 (256 LANs) or a /48 (65,536 LANs) from your ISP.

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.
