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.

How many bits are normally used to identify the subnet in an IPv6 address?
64 bits
What is the length in bits of a logical IP address IPv4 and IPv6?
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
How many number of bits are in the subnet 100?
A subnet with a prefix of /100 indicates that the first 100 bits of the IP address are fixed for the network portion. However, since IPv4 addresses are only 32 bits long, a subnet mask of /100 is not valid in this context. In IPv6, which allows for longer prefixes, a /100 subnet would have 100 bits dedicated to the network, leaving 28 bits for host addresses.
How many bits are in an IPv6?
IPv6 uses a 128-bit address space
How many bits are used for an IP address in IPv6?
IN IPv6 we can find 128bits.
Which address types are 128 bits in length?
IPv6 address
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 do you determine what bits to use to calculate the network address?
An IP address comes in two formats: ipV4 and ipV6. In IpV4 32 bits are allocated to the IP address. In IpV6, 128 bits are allocated to the address. This is done by the protocol and is a standard for developing an IP address.
What are the last 64 bits of a IPv6 address called?
The last 64 bits of an IPv6 IP address is called the Interface ID. These last 64 bits are used to uniquely identify an interface on the local link.
What are the last 64 bits of a IPv6 IP address called how are these bits used?
Interface ID
How many bits make up IPV4 subnet mask?
The subnet mask itself is an IP Address so it is also 32 bits
How many bits in an IP V6 address?
128 Bits. An IPv6 address is made up of 8 fields consisting of 16 bits per field. If you multiply 8 x 16 will get 128 bits. Each field is separated by colons unlike IPv4 which was separated by dotted decimal notation. A good link to go to to see the address and how sub-netting is done is on the related links below.
