Sure, we can add text for other usage scenarios. What about this:
A generic Internet address consists of two objects, one whose syntax
is InetAddressType, and another whose syntax is InetAddress. The
value of the first object determines how the value of the second
object is encoded. The InetAddress textual convention represents an
opaque Internet address value. The InetAddressType enumeration is
used to "cast" the InetAddress value into a concrete textual
convention for the address type. This usage of multiple textual
conventions allows expression of the display characteristics of each
address type and makes the set of defined Internet address types
extensible.
+ The textual conventions defined in this document can also be used to
+ represent generic Internet subnets and Internet address ranges. A
+ generic Internet subnet is represented by three objects, one whose
+ syntax is InetAddressType, a second one whose syntax is InetAddress
+ and a third one whose syntax is InetAddressPrefixLength. The
+ InetAddressType value again determines the concrete format of the
+ InetAddress value while the InetAddressPrefixLength identifies the
+ Internet network address prefix.
+
+ A generic range of consecutive Internet addresses is represented by
+ three objects. The first one has the syntax InetAddressType while
+ the remaining objects have the syntax InetAddress and specify the
+ start and end of the address range. The InetAddressType value again
+ determines the format of the InetAddress values.
