Which statement correctly describes the main addressing differences between IPv4 and IPv6?

Explanation:
Differences in address size and representation between IPv4 and IPv6 are what this item tests. IPv4 addresses are 32 bits long and written in dotted decimal notation, such as 192.0.2.1. IPv6 addresses are 128 bits long and written in hexadecimal with colon separators, such as 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Therefore, the correct statement is that IPv4 uses 32-bit addresses in dotted decimal; IPv6 uses 128-bit addresses in hexadecimal with colon separators. The other statements either swap sizes, misstate the notation, or claim interchangeability without routing changes, which does not reflect how IPv4 and IPv6 operate.
