What is IPv4 and IPv6?

A: IPv6 is the sixth revision to the Internet Protocol and the successor to IPv4. It functions similarly to IPv4 in that it provides the unique, numerical IP addresses necessary for Internet-enabled devices to communicate. However, it does sport one major difference: it utilizes 128-bit addresses.

Just so, what is difference between IPv4 & IPv6?

Differences between IPv4 and IPv6. Share the Article: One of the differences between IPv4 and IPv6 is the appearance of the IP addresses. IPv4 uses four 1 byte decimal numbers, separated by a dot (i.e., while IPv6 uses hexadecimal numbers that are separated by colons (i.e. fe80::d4a8:6435:d2d8:d9f3b11).

Is IPv4 or IPv6 faster?

The Unicast IPv6 RTT is faster than IPv4 for 48% of the time, but more than 10ms faster only 18% of the time. Similarly, the Unicast IPv6 RTT is slower than IPv4 for 51% of the time, and is more than 10ms slower 25% of the time.

What is IPv6 used for?

In IPv4, Host (A) records are used to map an IP address to a host name. DNS is still used in IPv6, but Host (A) records are not used by IPv6 addresses. Instead, IPv6 uses AAAA resource records, which are sometimes referred to as Quad A records. The domain ip6.arpa is used for reverse hostname resolution.
