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.
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 .
How many IP addresses are in a 48?
Because all IPv6 networks have /64 prefixes, a /48 network prefix allows 65,536 LANs in an End User’s site.
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?
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 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 by far the most popular DNS server software available?
Berkeley Internet Name Domain (BIND) is the most popular Domain Name System ( DNS ) server in use today.
How many IP addresses are in a 16?
CIDR, Subnet Masks, and Usable IP Addresses Quick Reference Guide (Cheat Sheet)
|CIDR||Subnet Mask||Total IPs|
What is a 64 subnet?
So a / 64 indicates that the first 64 bits of the 128-bit IPv6 address are fixed. The remaining bits ( 64 in this case) are flexible, and you can use all of them. This means that when your ISP gives you a / 64 they are giving you 2 64 addresses (that is 18,446,744,073,709,551,616 addresses).
What does 32 mean in IP address?
Generally speaking, / 32 means that the network has only a single IPv4 address and all traffic will go directly between the device with that IPv4 address and the default gateway. The device would not be able to communicate with other devices on the network.
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.
Why does a Layer 2 switch need an IP address?
Explanation:A switch , as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address . Routers, not switches , function as default gateways.
What is the range of IPv6 address?
IPv6 addresses are each 128 bits long. Because each digit in an IPv6 address can have 16 different values (from 0 to 15), each digit represents the overall value of 4 bits (one nibble), with 32 digits total. As with IPv4, CIDR notation describes ranges in terms of a common prefix of bits.
How many subnets are in a 24?
|Network Bits||Subnet Mask||Number of Subnets|
|/24||255.255 . 255.0||65536 (65534)|
|/25||255.255 .255.128||131072 (131070)|
|/26||255.255 .255.192||262144 (262142)|
|/27||255.255 .255.224||524288 (524286)|
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.
