What are the different types of IPv6 addresses?
Types of IPv6 addresses. There are three types of IPv6 addresses: Unicast, Anycast, and Multicast. Let's understand these address types in detail through an example. Unicast addresses. A unicast address represents a single interface in the network. It is used in end-to-end communication between two devices.
What are the parts of an IPv6 address?
The following are the three conventional forms used to represent the IPv6 addresses as text strings:
- Colon-hexadecimal form. This is the preferred form n:n:n:n:n:n:n:n. Each n represents the hexadecimal value of one of the eight 16-bit elements of the address. ...
- Compressed form. Due to the address length, it is common to have addresses containing a long string of zeros. ...
- Mixed form. This form combines IPv4 and IPv6 addresses. ...
What is meant by unicast address?
Unicast addresses are what you would call regular addresses. They are the addresses usually bound to your network card. Unicast addresses should be unique on a network, meaning a single unicast address should only represent a single system. Multicast addresses are used to make a one-to-many connection.
What are three types of unicast IPv6 address?
The three types of IPv6 addresses are: unicast, anycast, and multicast. Unicast addresses identify a single interface. Anycast addresses identify a set of interfaces in such a way that a packet sent to an anycast address is delivered to a member of the set.
What are two types of IPv6 unicast addresses?
The two regular types of unicast addresses include: Link-local address. Link-local addresses are designed for use on a single local link (local network). Link-local addresses are automatically configured on all interfaces.
What is meant by unicast?
Unicast is basically a single, direct request sent from one host to another, and only the two hosts interact over the established route. For example, when you click a hyperlink in a Web browser, you are requesting HTTP data from the host defined in the link, which, in turn, delivers the data to your browser.

How many bits are there in a subnet?
They can use a flat topology or can create a hierarchical topology by subnetting the subnet bits. After 54 subnet bits, the last 64 -bits are available for the Interface ID. The Interface ID field identifies a specific interface on a subnet.
How many bits are in a site local address?
In site-local addresses, the first 10 bits are always set to 1111 1110 11. In hexadecimal notation, these addresses start with FEC0::/10. After the first 10 bits, the next 54 -bits are available for local subnets. Administrators can use subnet bits to create subnets within the organization. They can use a flat topology or can create a hierarchical topology by subnetting the subnet bits. After 54 subnet bits, the last 64 -bits are available for the Interface ID. The Interface ID field identifies a specific interface on a subnet.

The next 16 bits are known as the subnet ID. The subnet ID is available for subnetting. Administrators can use subnet bits to create subnets or organize the site in a hierarchy. The next 64 bits are available for the interface ID. Interface ID makes each address unique in the subnet.
How many bits are allocated for unicast?
The first three bits of global unicast addresses are always set to 001. The next 45 bits are allocated by the Internet Register authorities.
What is a loopback address?
A loopback address is assigned to a loopback interface. A loopback interface is a virtual interface. It is commonly used for testing and debugging purposes. It allows the host device to send packets to itself. In IPv4, the loopback address is 127.0.0.1. In IPv6 the loopback address is 0:0:0:0:0:0:0:1 or ::1. Routers never forward packets sent on the loopback address.
What is a unicast address?
A unicast address identifies a single interface in the network. Packets sent to a unicast address are delivered to a single interface. There are five main types of unicast addresses in IPv6. These types are unspecified, loopback, link-local, site-local or unique local, and global.
What are the first seven bits of a unique address?
In unique local addresses the first seven bits, are always remain 1111 110. In hexadecimal, these bits are represented FC00::/7.
What is unique local?
Unique local − It is similar to a private address in IPv4 and not intended to be routable in the IPv6 Internet.
What is loopback in IPv6?
Loopback − In loopback an address not assigned to any physical interface which can be used for a host to send an IPv6 packet to itself.
What is unicast address?
So when the device sends the packet to a unicast address what happens is that the packet goes only to that specified interface that is being identified using the address.
What is global unicast?
Global unicast − Global unicast addresses are similar to public IPV4 addresses. It can be aggregated or summarized to produce an efficient routing infrastructure.
Why is IPv6 needed?
The need for IPv6 arises as this protocol can handle the packets more efficiently which thereby improve the performance and security. Most importantly it enables the service providers to reduce the size of their routing tables.
What is the difference between static and dynamic IP address?
The common difference between the static and the dynamic addressing is that the static address does not change whenever a device is assigned a static IP address whereas dynamic IP address is assigned by the network and changes over time.
How many bits are in IPv6?
IPv6 consists of 128 bits which are represented by eight groups of hexadecimal digits out of which each group is represented by 16 bits that are separated by colons.
What is IPv6 global address?
IPv6 global addresses are similar to IPv4 public addresses. As the name implies, they are routable on the internet. Currently IANA has assigned only 2000::/3 addresses to the global pool. A global IPv6 address consists of two parts: subnet ID – 64 bits long.
How long is a subnet ID?
subnet ID – 64 bits long. Contains the site prefix (obtained from a Regional Internet Registry) and the subnet ID (subnets within the site).
What is the table 4-6?
Table 4-6 shows the different formats for representing an IPv6 loopback address.
What is a loopback IPv6 address?
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.
What is a unicast address?
A unicast address uniquely identifies an interface on an IPv6 device. A packet sent to a unicast address is received by the interface that is assigned to that address. Similar to IPv4, a source IPv6 addresses must be a unicast address.
What is the format of a link-local unicast address?
Figure 4-8 shows the format of a link-local unicast address, which is in the range fe80::/10. Using this prefix and prefix length results in the range of the first hextet being from fe80 to febf.
What is a link local address?
A link-local address is a unicast address that is confined to a single link, a single subnet. Link-local addresses only need to be unique on the link (subnet) and do not need to be unique beyond the link. Therefore, routers do not forward packets with a link-local address.
Can NAT be used with IPv4?
Remember that the driving force for using NAT with IPv4 is not security but IPv4 address depletion. Although the IAB and the IETF did not intend for NAT to be used with IPv6 as it is with IPv4, NAT does provide mechanisms for translation where translation is necessary. These translation techniques include Network Prefix Translation version 6 (NPTv6), described in RFC 6296, IPv6-to-IPv6 Network Prefix Translation, and NAT66, described in an Internet draft RFC, IPv6-to-IPv6 Network Address Translation (long expired). Both of these RFCs focus on translation for address independence—and only where necessary. In RFC 6296, the IETF goes as far as stating, “For reasons discussed in [RFC 2993] and Section 5, the IETF does not recommend the use of Network Address Translation technology for IPv6.”
What is global routing prefix?
Global Routing Prefix: The Global Routing Prefix is the prefix or network portion of the address assigned by the provider, such as an ISP, to the customer site.
What is IPv6 unicast address?
An IPv6 unicast address is used to identify a single interface in a node. An IPv6 Unicast address identifies only one node in networks and unicast addresses are used for one to one communication. IPv6 Aggregate Global Unicast Addresses are similar to IPv4 public addresses. Aggregate Global Unicast Addresses are globally routable addresses on IPv6 Internet. RFC 3587 defines the usable range of IPv6 global unicast addresses. RFC 3587 states that out of the 128 bits in IPv6 addresses, left most three bits are must be fixed as 001. Remaining 45 bits are reserved for global routing prefix. 16 bits after that can be used for subnetting and the 64 remaning bits are the host bits.
How many bits are used in IPv6?
Which means that, currently first 48 bits of an IPv6 address are used to identify the network globally. The next 16 bits are used for subnetting (which makes 48+16=64 bits, network part) and the remaining 64 bits are used for identifying the hosts (host part).
What Does Unicast Address Mean?
A unicast address is an address that identifies a unique node on a network. Unicast addressing is available in IPv4 and IPv6 and typically refers to a single sender or a single receiver, although it can be used in both sending and receiving. A unicast address packet is transferred to a network node, which includes an interface address.
Techopedia Explains Unicast Address

A link-local unicast address has the prefix fe80::/10 in standard IPv6 addressing scehme and following are the cases with meaning of address used
What is the prefix for IPv6?
ff00::/8 This prefix is offered by IPv6 to denote the multicast addresses. Any address carrying this prefix is automatically understood to be a multicast address.
What is fc00::/7?
fc00::/7 This is called the Unique Local Address (ULA). These addresses are routed only within a set of cooperating sites. These were introduced in the IPv6 to replace the site-local addresses. These addresses also provide a 40-bit pseudorandom number that reduces the risk of address conflicts.
What is the cdba:9abc:5678::/64?
2001:cdba:9abc:5678::/64 denotes the network address 2001:cdba:9abc:5678. This network comprises of addresses rearranging from 2001:cdba:9abc:5678:: up to 2001:cdba:9abc:5678:ffff:ffff:ffff:ffff. In a similar fashion, a single host may be denoted as a network with a 128-bit prefix. In this way, IPv6 allows a network to comprise of a single host and above.
Is fe80::/10 a link-local prefix?
Answers 3 is correct is because fe80::/10 is a link-local prefix offered by IPv6. This address prefix signifies that the address is valid only in the local physical link.An IPV6 Unicast address acts as an identifier for a single interface. An IPv6 packet sent to a Unicast address is delivered to the interface identified by that address.IPv6 addresses are denoted by eight groups of hexadecimal quartets separated by colons in between them.
