# What is IPv6 addressing format?

## What is IPv6 addressing format?

An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits The groups are separated by colons (:). An example of an IPv6 address is: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The standards provide flexibility in the representation of IPv6 addresses.

## How do you write an IPv6 address?

Specify IPv6 addresses by omitting leading zeros. For example, IPv6 address 1050:0000:0000:0000:0005:0600:300c:326b can be written as 1050:0:0:0:5:600:300c:326b .

IPv6 addresses An Ipv6 address uses 128 bits as opposed to 32 bits in IPv4. Because an hexadecimal number uses 4 bits this means that an IPv6 address consists of 32 hexadecimal numbers. These numbers are grouped in 4’s giving 8 groups or blocks. The groups are written with a : (colon) as a separator.

### How is an IPv6 address written and displayed?

IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses. IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus (8 x 16 = 128) bits in total.

### How do I know what IPv6 address?

As Table 1 shows, you can quickly determine which type of IPv6 address you are dealing with by looking at the beginning part of the address-that is, the high-order bits of the address. Tables 2 and 3 also show examples of common IPv6 addresses that you can recognize directly from their colon-hexadecimal representation.

Why do I have 3 IPv6 addresses?

You will get a different IPv6 address for each unique interface/MAC address. So your wifi and cellular will have two different ones. Once you VPN to a network, you will get a third IPv6.

What are the four main IPv6 address types?

A single interface can be assigned multiple IPv6 addresses of any type. The three types of IPv6 addresses are: unicast, anycast, and multicast. Unicast addresses identify a single interface.

#### What are the three parts of an IPv6?

Explanation:There are three elements that make up an IPv6 global unicast address. A global routing prefix which is provided by an ISP, a subnet ID which is determined by the organization, and an interface ID which uniquely identifies the interface interface of a host.

#### What makes an IPv6 address valid?

An IPv6 (normal) address has the format y:y:y:y:y:y:y:y, where y is called a segment and can be any hexadecimal value between 0 and FFFF. The segments are separated by colons, not periods. The following are examples of valid IPv6 (normal) addresses: 2001:db8:3333:4444:5555:6666:7777:8888.
