I have been a Sirius subscriber since it became available in Canada. If I had bought two lifetime subscriptions at that time I would be breaking even by now. I totally think it is worth the small price even though some things were downgraded after the merger with XM.
Class D: The IP addresses in this class are reserved for a service called Multicast. Class E: The IP addresses in this class are reserved for experimental use. Broadcast: This is the special network of 255.255.255.255, and is used for broadcasting messages to the entire network that your computer resides on.here are some guidelines to to how IP address can appear, though. The four numbers must be between 0 and 255, and the IP address of 0.0.0.0 and 255.255.255.255 are reserved, and are not considered usable IP addresses. IP addresses must be unique for each computer connected to a network.
Note Class A. This was before CIDR. So, the Class A, B and C private address netblocks needed to come out of the correct IP ranges. I know that 172.16.0.0/12 was picked because it offered the most continuous block of Class B (/16) addresses in the IP space that was in a reserved block. know the concept of public IP, private IP ranges and its purpose. But a guy asked me couple of days back why particular range is choosen as private over other. I think its a Randon pick as they wanted to give private range for users(companies) from each class of network.
