global unicast address
IPv6 address has 2^128 address and IPv6 address is of 16 bytes and is represented in colon hex notation.
The DNS resource record used to contain IPv6 addresses of nodes is called the AAAA record (pronounced "quad-A"). This record maps a domain name to its corresponding IPv6 address, allowing systems to resolve domain names to their IPv6 addresses for proper routing and connectivity over the internet.
IN IPv6 we can find 128bits.
IPv6 uses a 128-bit address space
The IPv6 equivalent of the IPv4 loopback address 127.0.0.1 is ::1. This address is used to refer to the local host in IPv6, similar to how 127.0.0.1 functions in IPv4. The "::" notation represents a shorthand for consecutive blocks of zeros in IPv6 addressing.
No, IPv6 addresses are not 64-bit; they are 128 bits in length. An IPv6 address is typically represented as eight groups of four hexadecimal digits, which makes it significantly larger than the 32-bit IPv4 addresses. The 128-bit structure allows for a vastly larger address space, accommodating the growing number of devices connected to the internet.
IPv6 address
To enable IPv6 forwarding and configure interface addressing on a Cisco router moving to an IPv6 environment, you would first enter global configuration mode and enable IPv6 routing with the command ipv6 unicast-routing. Next, you would access the specific interface using interface <interface-name> and assign an IPv6 address with the command ipv6 address <ipv6-address>/<prefix-length>. Finally, use the command no shutdown to activate the interface.
To verify TCP IPv6 protocols, you can ping the loopback address, which is ::1. This address is used to test the local network stack of the device itself. Additionally, you can ping a well-known IPv6 address, such as 2001:4860:4860::8888, which is a Google Public DNS server, to check connectivity over IPv6.
IPv6 addresses are represented as eight groups of four hexadecimal digits, separated by colons. Each group corresponds to 16 bits, making the total length of an IPv6 address 128 bits. For example, an IPv6 address may look like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Hexadecimal notation allows for a compact representation of binary data, making it suitable for addressing in networking contexts.
