Subject: Remove special chapter about IPv6 address formats from ARM

Remove special chapter about IPv6 address formats from ARM

In 2022, IPv6 is not anything unusual, and it was really odd
to have it in a separate section next to a huge list of RFCs.

Fixes: #1918

-IPv6 Addresses (AAAA)
----------------------
-
-IPv6 addresses are 128-bit identifiers, for interfaces and sets of
-interfaces, which were introduced in the DNS to facilitate scalable
-Internet routing. There are three types of addresses: *Unicast*, an
-identifier for a single interface; *Anycast*, an identifier for a set of
-interfaces; and *Multicast*, an identifier for a set of interfaces. Here
-we describe the global Unicast address scheme. For more information, see
-:rfc:`3587`, "IPv6 Global Unicast Address Format."
-
-IPv6 unicast addresses consist of a *global routing prefix*, a *subnet
-identifier*, and an *interface identifier*.
-
-The global routing prefix is provided by the upstream provider or ISP,
-and roughly corresponds to the IPv4 *network* section of the address
-range. The subnet identifier is for local subnetting, much like
-subnetting an IPv4 /16 network into /24 subnets. The interface
-identifier is the address of an individual interface on a given network;
-in IPv6, addresses belong to interfaces rather than to machines.
-
-The subnetting capability of IPv6 is much more flexible than that of
-IPv4; subnetting can be carried out on bit boundaries, in much the same
-way as Classless InterDomain Routing (CIDR), and the DNS PTR
-representation ("nibble" format) makes setting up reverse zones easier.
-
-The interface identifier must be unique on the local link, and is
-usually generated automatically by the IPv6 implementation, although it
-is usually possible to override the default setting if necessary. A
-typical IPv6 address might look like:
-``2001:db8:201:9:a00:20ff:fe81:2b32``.
-
-IPv6 address specifications often contain long strings of zeros, so the
-architects have included a shorthand for specifying them. The double
-colon (``::``) indicates the longest possible string of zeros that can
-fit, and can be used only once in an address.
