Given the following IP address:f061:c9f1:3e67:8acb:ce1d:5a03:5a6c:9952Do not enter any leading or ending colons.Identify the prefix:Identify the subnet ID:

The question seems to be incomplete. In an IPv6 address, the prefix and subnet ID are not directly visible or extractable from the address itself like the way you've asked. They are determined by the network's configuration.

Typically, an IPv6 address is written in this format: [IPv6 Address]/[Prefix length]. The prefix length, ranging from 0 to 128, indicates the number of bits in the address that are the network part. The rest is the host part.

For example, in the address "2001:0db8:85a3:0000:0000:8a2e:0370:7334/64", "2001:0db8:85a3:0000:0000:8a2e:0370:7334" is the IPv6 address and "64" is the prefix length.

The subnet ID is part of the IPv6 address and is used to identify networks under a single organization. It's the part of the address between the global routing prefix and the interface ID.

Without the prefix length and more information about the network's structure, it's impossible to identify the prefix and subnet ID from the IPv6 address "f061:c9f1:3e67:8acb:ce1d:5a03:5a6c:9952".
