Readers ask: How many subnets can a /48 site prefix support?

How many IP addresses are in a 48?

IPv6 Relative Network Sizes

/128 1 IPv6 address
/56 256 LAN segments
/48 65,536 LAN segments
/32 65,536 /48 subscriber sites
/24 16,777,216 subscriber sites

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.

How do you calculate the number of subnets needed?

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.

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.

What is a 64 subnet?

The /64 is the prefix length. It is the number of bits in the address that is fixed. 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.

How many 64 networks can be assigned from a 48 network address prefix?

Large customers get a /48 prefix. That gives them 65,536 /64 subnets. Medium customers get a /56 prefix. That gives them 256 /64 subnets.

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 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 is IP subnet?

A subnetwork or subnet is a logical subdivision of an IP network. 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. The rest field is an identifier for a specific host or network interface.

How many octets is an IP address?

An IP address is, as such, generally shown as 4 octets of numbers from 0-255 represented in decimal form instead of binary form.
