Final answer:
An IPv6 address that begins with '1' is typically a Global Unicast Address, which is globally unique and functions like a public IP in IPv4.
Step-by-step explanation:
The type of IPv6 address that begins with the numeral '1' is typically a Global Unicast Address. These addresses are globally unique and are equivalent to public IP addresses in IPv4. The structure of an IPv6 address is 128 bits long, divided into eight 16-bit blocks. Each block is written as four hexadecimal digits and the blocks are separated by colons. In a Global Unicast Address, the first three bits of the address are set to '001', which can result in the first hexadecimal digit of the address being '1', '3', '9', 'b', 'd', or 'f'. However, it's worth noting that not all IPv6 addresses that start with '1' are Global Unicast Addresses; the full address needs to be examined to determine its type.
