![]() Tdc has BGP AS 3292 - two octet AS number necessary.Ĭonverting 3292 to binary gives 110011011100 seperate it to two binary octets 00001100 11011100 and converting each octet separately to decimal gives 12 and 220, giving tdc the GLOP addresses 233.12.220.x, where x defines locally assigned bits. The GLOP IPv4 address is built in octet two and three from the providers BGP AS number. If the content provider does not have its own assigned ASN, usually it can lease static GLOP addresses from their Internet Service Provider. Content providers who wish to transmit multicast traffic to their customers in the Internet and that have an assigned Autonomous System Number (ASN) can use multicast addresses from their block of 255 static GLOP addresses to transmit content. This allocation methodology, called GLOP addressing, which is defined in RFC 2770, uses the multicast group range of 233.0.0.0 through 233.255.255.255 (233/8) and provides each Autonomous System with a block of 255 statically assigned multicast addresses. This block of addresses has been assigned by the IANA as an experimental, statically assigned range of multicast addresses intended for use by Content Providers, ISPs, or anyone wishing to source content into the global Internet. Established by the Internet Engineering Task Force (IETF) to multicast audio and video meetings, Mbone is a collection of Internet routers that support IP multicasting on which various public and private audio and video programs are sent.
