## Which is a valid IPv6 address?

The following are examples of valid IPv6 (normal) addresses: 2001:db8:3333:4444:5555:6666:7777:8888. 2001:db8:3333:4444:CCCC:DDDD:EEEE:FFFF.

## Which is a valid IPv6 address Mcq?

IPv6 MCQ Question 1 Detailed Solution

The correct answer is option 2 i.e 128 bits. An IPv6 address has a size of 128 bits.

## How many IPv6 addresses are there?

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.

## Which of the following are invalid IPv6 addresses?

The addresses 255.1. 4.2 and fe80:2030:31:24 are not valid IPv6 addresses. colons separating each 2-byte segment. IPv6 addresses are 16 bytes, or 128 bits in length.

## What are the 3 types of IPv6 addresses MCQs?

Just as with IPv4, a single device’s interface can have more than one address; with IPv6 there are more types of addresses and the same rule applies. There can be link-local, global unicast, and multicast addresses all assigned to the same interface.

## Why are there 3 IPv6 addresses?

Of the two public addresses, the first one is SLAAC (always the same, and resembles the one in fe80), the other one is the “privacy” one (changes every X hours). If you let your device on long enough, one of the addresses will “expire” and you will get a new privacy address.

Answers Explanation & Hints: IPv6 LLAs are in the fe80::/10 range. The /10 indicates that the first 10 bits are 1111 1110 10xx xxxx.

## How do I find IPv6 address?

Type “ipconfig/all” on the blinking cursor then press [Enter]. NOTE: You will find the IPv6 Address network details under the Ethernet adapter Local Area Connection section.

## Why do I have 4 IPv6 addresses?

Suffice to say that, if you 4 IPv6 addresses, you are using both Link Local and Global addresses – and your DHCPv6 DHCP server is operating in Stateless mode.

## 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 is IPv4 address example?

IP (version 4) addresses are 32-bit integers that can be expressed in hexadecimal notation. The more common format, known as dotted quad or dotted decimal, is x.x.x.x, where each x can be any value between 0 and 255. For example, 192.0. 2.146 is a valid IPv4 address.

## What is IPv6 used for?

Internet Protocol Version 6 (IPv6) is a network layer protocol which allows communication and data transfers to take place over the network. IPv6 came into existence in 1998 with the sole purpose to take over and replace IPv4 protocol one day.

## Why do I have 2 ip6 addresses?

Because new addresses are generated regularly the addresses are marked as temporary . A device can have multiple privacy extension addresses if the system is still using an old address when a new address is being generated. The system will keep the old address for as long as necessary.

## How do I know if my IPv6 address is valid?

Typically strings, that do *not* trepresent a valid IPv6 address have characters other than the hex-digits in it, or they consists of less than 8 blocks of hexdigits, or they have at least one block of hexdigits in it with more than 4 hex-digits, or they have more than one position in it, where 2 colons directly follow …

## What is IPv4 and IPv6 address?

The main difference between IPv4 and IPv6 is the address size of IP addresses. The IPv4 is a 32-bit address, whereas IPv6 is a 128-bit hexadecimal address. IPv6 provides a large address space, and it contains a simple header as compared to IPv4.

## Which of the following is an invalid IPv4 address?

0.0″ and “255.255. 255.255.” Another number, “127.0. 0.1” is called the “localhost;” every computer on a network refers to itself as this address. Because these numbers have special meanings, the network does not assign them to PCs; such addresses would be invalid.

## Which one of these are valid IPv4 address check all that apply?

Answer: IPV4, the traditional numbering scheme, uses four integers ranging from zero to 255 and set apart by periods. For example, “204.120. 0.15″ is a valid IPV4 address.
