The IPv6 address space includes several reserved blocks and private-use addresses. Here’s a breakdown of the main IPv6 address types and their purposes:

Reserved IPv6 Address Ranges

::/128: Unspecified address. This is used when an interface does not yet have an assigned address (similar to 0.0.0.0 in IPv4)(IANA)(Wikipedia).
::1/128: Loopback address. It’s used to refer to the local device, similar to 127.0.0.1 in IPv4(IANA)(Wikipedia).
fc00::/7: Unique Local Addresses (ULA). These addresses are used within private networks. They are not globally routable but are unique within a specific local network(IANA)(IPCisco).
fe80::/10: Link-local addresses. These addresses are used within a single link (subnet). Devices automatically assign these addresses for communication within the local network (non-routable)(IPCisco)(Wikipedia).
ff00::/8: Multicast addresses. These are used for one-to-many communication in an IPv6 network(IANA)(Wikipedia).
2001:db8::/32: Documentation addresses. These are reserved for use in technical examples and documentation(IANA).

Globally Routable Addresses (only this addresses are used on this tests)

2000::/3: This is the global unicast address space used for devices on the public internet. All IPv6 addresses meant for general public use come from this block(IANA)(IANA).

IPv6 Special-Purpose Addresses

There are various address blocks allocated for special purposes, such as IPv4-IPv6 translation, IETF protocol assignments, and benchmarking(

IANA).

These reserved and special-purpose IPv6 addresses help ensure that certain address ranges have specific uses, improving network functionality and routing efficiency. When practicing IPv6 subnetting, it’s important to avoid using these reserved ranges unless specifically required for testing or special use cases.
