Link-local
addresses cannot be used for communication across different networks or routed
over the internet. They are strictly limited to the local link, which ensures
that the addresses are used only for local interactions.

These are globally unique addresses that can be routed on the public internet. Every device that needs direct internet access is assigned a global unicast address. Typically begins with 2000::/3. That is any address starting with 2 or 3. For example, 2001:0db8:85a3::8a2e:0370:7334

One of the three methods of sending data in an IPv6 network is Unicast. It is a one to one communication type where a packet is sent from one source address to one specific destination address like Link-local addresses and Global Unicast addresses. How best could you explain these 2 examples of Unicast addresses with examples?

IPv6 is intended to replace IPv4 by providing a larger address space, enhanced performance, and improved security. With its native support for security, IPv6 was designed with security in mind. It includes IPsec as a mandatory component, providing data integrity, confidentiality, and authentication for communications at the IP layer. However…

IPv4 has lasted this long because NAT was introduced to extend the lifetime of IPv4 by allowing multiple devices on a private network to share a single public IP address. This helped conserve public IPv4 addresses, delaying the exhaustion of the IPv4 address pool. However, it is not sustainable because of its limited address space, 32…

IPv6(Internet protocol version 6) is the latest of internet protocol designed to replace IPv4, the previous version. It uses 128-bit addresses, providing a vastly larger address space compared to IPv4’s 32-bit addresses. There are several reasons why we need IPv6, one which is its provision of better security with a built-in IPsec and…
