How many bits are in the Subnet ID blocks and what are the values of these bits for a link-local IP address?
16 bits per block
What is the difference between the subnet mask for a Class A address with 16 bits for the subnet ID and a class B address with 8 bits for the subnet ID?
In a Class A address, the default subnet mask is 255.0.0.0, allowing for a large number of hosts within a single network, but with 16 bits designated for the subnet ID, the subnet mask becomes 255.255.0.0. In contrast, a Class B address has a default subnet mask of 255.255.0.0, and with 8 bits for the subnet ID, the subnet mask would typically be 255.255.255.0. Thus, the key difference lies in the number of bits allocated for the subnet ID and the resulting subnet masks, affecting the number of available subnets and hosts per subnet.
How you create subnet id for a particular id?
To create a subnet ID, you start with the network's base IP address and subnet mask. The subnet mask determines how many bits are allocated for the network and how many for the hosts. By applying the subnet mask to the base IP address, you can identify the subnet ID, which represents the network portion of the address. For example, if your base IP is 192.168.1.0 with a subnet mask of 255.255.255.0, the subnet ID is 192.168.1.0.
How many bits are in the subnet ID block and What are the values of these bits for a link-local IP address?
16 bits per block
Multicast address IPv6 subnet ID is how many bits long?
In IPv6, the multicast address subnet ID is 64 bits long. This is part of the overall 128-bit address structure, where the first 8 bits are reserved for the multicast prefix (FF00::/8), followed by 16 bits for flags and scope, and the remaining 64 bits represent the group ID. Thus, the group ID allows for a large number of multicast groups within the IPv6 space.
What would the subnet mask be if the first 24 bits of the ip address represent the network id?
The subnet mask would be 255.255.255.0
How many bits are in the subnetted ID 185.27.54.0?
To determine the number of bits in the subnetted ID of 185.27.54.0, you need to know the subnet mask used. However, if it’s a standard Class B address (which uses a default mask of 255.255.0.0), it has 16 bits for the network portion. If the address is subnetted further, additional bits are borrowed from the host portion, increasing the network bit count. For example, if a subnet mask of 255.255.255.0 is used, then there would be 24 bits in the subnetted ID.
For an IP address what component decides the number of bits that is used to represent the host ID?
Subnet mask.
How do you know which bits are host bit in a subnet mask?
Since a subnet mask is used to separate the network id from the host id, any 1 bits indicate the network portion and the 0 bits indicate host portion. As an example, in the subnet mask: 255.255.0.0 This indicates the first two octets are used for the network, and the last two octets (ipV4) are used for host portion of an address.
What is the combination of additional bits used for subnet information plus the existing network ID called?
It depends on the book, but is usually known as the extended network prefix.
How many hosts and subnets are possible if you have an IP of 151.242.16.49 with a subnet mask of 7 bits?
151.242.16.49 would be class B in a classful environment with a network mask of 16 bits. An additional 7 bit subnet mask puts the total mask at 23 (i.e.: 255.255.254). Subnet ID would be: 151.242.16.0 Host address range: 151.242.16.1 through 151.242.17.254 Subnet Broadcast address would be: 151.242.17.255
If you have been assigned network ID 172.16.50 with a subnet mask of 255.255.255.0 What is the maximum number of workstations you can have on the subnet?
Since this is a class B network you have borrowed 8 bits for subnets. This leaves 8 bits left (1 octet) for clients/workstations. That gives you a maximum of 254 clients per subnet.
