-/// # Embedding IPv4 Addresses
-///
-/// See [`IpAddr`] for a type encompassing both IPv4 and IPv6 addresses.
-///
-/// To assist in the transition from IPv4 to IPv6 two types of IPv6 addresses that embed an IPv4 address were defined:
-/// IPv4-compatible and IPv4-mapped addresses. Of these IPv4-compatible addresses have been officially deprecated.
-///
-/// Both types of addresses are not assigned any special meaning by this implementation,
-/// other than what the relevant standards prescribe. This means that an address like `::ffff:127.0.0.1`,
-/// while representing an IPv4 loopback address, is not itself an IPv6 loopback address; only `::1` is.
-/// To handle these so called "IPv4-in-IPv6" addresses, they have to first be converted to their canonical IPv4 address.
-///
-/// ### IPv4-Compatible IPv6 Addresses
-///
-/// IPv4-compatible IPv6 addresses are defined in [IETF RFC 4291 Section 2.5.5.1], and have been officially deprecated.
-/// The RFC describes the format of an "IPv4-Compatible IPv6 address" as follows:
-///
-/// ```text
-/// | 80 bits | 16 | 32 bits |
-/// +--------------------------------------+--------------------------+
-/// |0000..............................0000|0000| IPv4 address |
-/// +--------------------------------------+----+---------------------+
-/// ```
-/// So `::a.b.c.d` would be an IPv4-compatible IPv6 address representing the IPv4 address `a.b.c.d`.
-///
-/// To convert from an IPv4 address to an IPv4-compatible IPv6 address, use [`Ipv4Addr::to_ipv6_compatible`].
-/// Use [`Ipv6Addr::to_ipv4`] to convert an IPv4-compatible IPv6 address to the canonical IPv4 address.
-///
-/// [IETF RFC 4291 Section 2.5.5.1]: https://datatracker.ietf.org/doc/html/rfc4291#section-2.5.5.1
-///
-/// ### IPv4-Mapped IPv6 Addresses
-///
-/// IPv4-mapped IPv6 addresses are defined in [IETF RFC 4291 Section 2.5.5.2].
-/// The RFC describes the format of an "IPv4-Mapped IPv6 address" as follows:
-///
-/// ```text
-/// | 80 bits | 16 | 32 bits |
-/// +--------------------------------------+--------------------------+
-/// |0000..............................0000|FFFF| IPv4 address |
-/// +--------------------------------------+----+---------------------+
-/// ```
-/// So `::ffff:a.b.c.d` would be an IPv4-mapped IPv6 address representing the IPv4 address `a.b.c.d`.
-///
-/// To convert from an IPv4 address to an IPv4-mapped IPv6 address, use [`Ipv4Addr::to_ipv6_mapped`].
-/// Use [`Ipv6Addr::to_ipv4`] to convert an IPv4-mapped IPv6 address to the canonical IPv4 address.
-/// Note that this will also convert the IPv6 loopback address `::1` to `0.0.0.1`. Use
-/// [`Ipv6Addr::to_ipv4_mapped`] to avoid this.
-///
-/// [IETF RFC 4291 Section 2.5.5.2]: https://datatracker.ietf.org/doc/html/rfc4291#section-2.5.5.2
-///
-/// # Textual representation
-///
-/// `Ipv6Addr` provides a [`FromStr`] implementation. There are many ways to represent
-/// an IPv6 address in text, but in general, each segments is written in hexadecimal
-/// notation, and segments are separated by `:`. For more information, see
-/// [IETF RFC 5952].
-///
-/// [`FromStr`]: crate::str::FromStr
