Автономная система и мультикаст адреса диапазон адресов

Коллеги,

 

Где можно узнать, какой диапазон мультикаст адресов закреплен за твоей автономной системой? Насколько я помню, при выделении номера AS, за тобой закрепляется определенный уникальный диапазон мультикаст адресов.

3. Address Space

  The IANA has allocated 223/8 as per RFC 2770 [RFC2770].  RFC 2770
  describes the administration of the middle two octets of 233/8 in a
  manner similar to that described in RFC 1797:

      0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
     |      233      |           16 bits AS          |  local bits   |
     +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

3.1. Example

  Consider, for example, AS 5662.  Written in binary, left padded with
  0s, we get 0001011000011110.  Mapping the high order octet to the
  second octet of the address, and the low order octet to the third
  octet, we get 233.22.30/24.
