/**
 *<pre> <b>8.38. Redirect-Address-Type AVP</b>
 *
 *
 *   The Redirect-Address-Type AVP (AVP Code 433) is of type Enumerated
 *   and defines the address type of the address given in the Redirect-
 *   Server-Address AVP.
 *
 *   The address type can be one of the following:
 *
 *   <b>IPv4 Address                    0</b>
 *      The address type is in the form of "dotted-decimal" IPv4 address,
 *      as defined in [IPv4].
 *
 *   <b>IPv6 Address                    1</b>
 *      The address type is in the form of IPv6 address, as defined in
 *      [IPv6Addr].  The address is a text representation of the address
 *      in either the preferred or alternate text form [IPv6Addr].
 *      Conformant implementations MUST support the preferred form and
 *      SHOULD support the alternate text form for IPv6 addresses.
 *
 *   <b>URL                             2</b>
 *      The address type is in the form of Uniform Resource Locator, as
 *      defined in [URL].
 *
 *   <b>SIP URI                         3</b>
 *      The address type is in the form of SIP Uniform Resource
 *      Identifier, as defined in [SIP].
 *      </pre>
