Which of the following are a valid IPv6 addresses?
The following list shows examples of valid IPv6 (Normal) addresses: 2001 : db8: 3333 : 4444 : 5555 : 6666 : 7777 : 8888. 2001 : db8 : 3333 : 4444 : CCCC : DDDD : EEEE : FFFF.
Which of the following are valid IPv6 addresses? An IPv6 IP address is a 128-bit address listed as eight 16-bit hexadecimal sections. Leading zeros can be omitted in each section. Therefore, 6384:1319:7700:7631:446A:5511:8940:2552 and 141:0:0:0:15:0:0:1 are both valid IPv6 addresses.
The three types of IPv6 addresses are: unicast, anycast, and multicast. Unicast addresses identify a single interface.
G. Explanation: The addresses 255.1. 4.2 and fe80:2030:31:24 are not valid IPv6 addresses.
* :: is the IPv6 "unspecified address." It is a unicast address not assigned to any interface, and is used by a DHCP -dependent host prior to allocating a real IPv6 address. * 2001:0:42:3:ff::1 is a valid IP address, with the :: representing two segments (4 bytes) of compressed zeros.
IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP 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.
A valid IPv4 address consists of 4 8-bit (1 byte) numbers separated by periods. For example, 10.0. 0.65. Because they are 8 bits long, these numbers are frequently called octets.

IPv6 link-local addresses are addresses that can be used to communicate with nodes (hosts and routers) on an attached link. Packets with those addresses are not forwarded by routers.
Which is a valid IPv6 address Mcq?
The correct answer is option 2 i.e 128 bits. An IPv6 address has a size of 128 bits.
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 ...
B IPv4 addresses are in dotted decimal format. Each decimal must be between 0 and 255. You cannot use 256, since 256 is not a valid number in an IPv4 address.
| Address type | Binary prefix | IPv6 notation |
|---|---|---|
| Unspecified | 00 . . . 0 (128 bits) | ::/128 |
| Loopback | 00 . . . 1 (128 bits) | ::1/128 |
| Multicast | 11111111 | FF00::/8 |
| Link-local unicast | 1111111010 | FE80::/10 |
| Prefix | IPv4 equivalent |
|---|---|
| fc00::/7 Example: fdf8:f535:82e4::53 | Private, or RFC 1918 address space: 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 |
| fe80::/10 Example: fe80::200:5aee:feaa:20a2 | 169.254.0.0/16 |
| 2001:0000::/32 Example: 2001:0000:4136:e378:8000: 63bf:3fff:fdd2 | No IPv4 equivalent |
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.
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.

There are four types of IP addresses: public, private, static, and dynamic.
Which is a valid IP address?
A valid IP address must be in the form of A.B.C.D, where A, B, C, and D are numbers from 0-255. The numbers cannot be 0 prefixed unless they are 0. Examples : Input: 25525511135 Output: [“255.255.
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.
Explanation: 128.64. 0.0 is correct IPv4 address because IPv4 is a standard numbering system that uses four integers from 0 to 255.
Since the leftmost three bits are reserved as "001" for Global unicast IPv6 addresses, the range of Global Unicast Addresses available now are from 2000 to 3FFF, as shown below. Global Unicast Addresses prefixes: The prefix is the part of the IPv6 address that indicates the network.
| Class | Total Network ID Bits | Possible Hosts |
|---|---|---|
| A | *8 | 224 - 2 = 16,277,214 |
| B | *16 | 216 - 2 = 65,534 |
| C | *24 | 28 - 2 = 254 |
The hosts will still send and receive traffic, but traffic may not always reach the correct destination. What IPv6 field is similar to the TTL field in IPv4 packets? Routing Information Protocol (RIP) is an interior gateway protocol that uses a link-state algorithm.
The Google Public DNS IPv6 addresses are as follows: 2001:4860:4860::8888. 2001:4860:4860::8844.
A valid IP address must be in the form of A.B.C.D, where A,B,C and D are numbers from 0-255. The numbers cannot be 0 prefixed unless they are 0. Note:You only need to implement the given function.
Use ipv6 if on Host A to obtain the link-local address for the Ethernet interface. Example: The link-local address of Host A is fe80::210:5aff:feaa:20a2. Use ipv6 if on Host B to obtain the link-local address for the Ethernet interface.
IPv6 private address ranges: fc00::/7 address block = RFC 4193 Unique Local Addresses (ULA) fec0::/10 address block = deprecated (RFC 3879)
What are the 3 types of IPv6 addresses Mcq?
Answer & Solution
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.
9. IPv6 does not use ________ type of address. Explanation: There is no concept of broadcast address in IPv6.
Which statement(s) about IPv6 addresses are true? Explanation: In order to shorten the written length of an IPv6 address, successive fields of zeros may be replaced by double colons. In trying to shorten the address further, leading zeros may also be removed.
Answers Explanation & Hints: IPv6 LLAs are in the fe80::/10 range. The /10 indicates that the first 10 bits are 1111 1110 10xx xxxx.
An IPv6 multicast address defines a group of devices known as a multicast group. IPv6 multicast addresses use the prefix ff00::/8, shown in Table 4-10, which is equivalent to the IPv4 multicast address 224.0. 0.0/4. A packet sent to a multicast group always has a unicast source address.
IPv6 (Internet Protocol Version 6) is also called IPng (Internet Protocol next generation) and it is the newest version of the Internet Protocol (IP) reviewed in the IETF standards committees to replace the current version of IPv4 (Internet Protocol Version 4).
Loopback Addresses
An IPv6 loopback address is ::1, an all-0s address except for the last bit, which is set to 1. It is equivalent to the IPv4 address block 127.0. 0.0/8, most commonly the 127.0. 0.1 loopback address.
