Address Ranges

An Address Range contains the following attributes:

Routing Entity Type
Start Address
End Address
Destination

RBAR Address Ranges are at least two addresses.

A common set of Address Ranges (such as all IMSIs associated with a LTE-HSS) is called a Digit Range Table (DRT).

For a DRT that can be associated with User Identity Types,

RBAR supports DRT Address Ranges with different digit lengths.
or example, the range 9195550000 - 9195559999 and the range 303200 - 303299 are allowed in the same DRT.
RBAR supports a minimum of 8 different DRT Address Range digit lengths.
For example, an MSISDN DRT could contain Address Ranges with 3 digits, 6 digits, 10 digits and 15 digits.

For a DRT that can be associated with the Routing Entity Type "IPv6-Prefix Address" , RBAR supports a minimum of 32 different DRT Address Range bit lengths.

For example, a DRT with the Routing Entity Type "IPv6-Prefix Address" could contain address ranges with 4 bits, 8 bits, 12 bits, …, 128 bits.

The "Start Address" and the "End Address" attributes of an Address Range entry that can be associated with the Routing Entity Type "UNSIGNED16" will always be a 16-bit value.
