Key Points
- IPv6 addresses do not require leading zeros, and in fact, leading zeros can be omitted to simplify the address. For example, the address "2001:0db8:0000:0000:0000:ff00:0042:8329" can be written as "2001:db8::ff00:42:8329".
- IPv6 addresses use the double colon (::) notation to represent a consecutive sequence of zero-value fields, but this notation is not used to separate all fields. It is used to compress the zeros in the address. For example, "2001:0db8:0000:0000:0000:ff00:0042:8329" can be compressed to "2001:db8::ff00:42:8329".
- Therefore, the given options 1) and 2) are partially incorrect or misleading, and neither of them individually nor in combination (option 3) correctly describe the characteristics of IPv6 addresses.
Additional Information
- IPv6 addresses are 128 bits long, compared to IPv4's 32 bits, allowing for a vastly larger number of addresses.
- IPv6 addresses are written in hexadecimal and separated by colons, for example, "2001:0db8:85a3:0000:0000:8a2e:0370:7334".
- IPv6 supports autoconfiguration, which can simplify the deployment and management of network devices.
- IPv6 includes enhancements over IPv4, such as improved security features and more efficient routing.
