Learn Windows XP Professional: TCP/IP Addressing in Windows XP Professional (Page 5) Page 5

TCP/IP Class D Address Overview

The IP
version 4 addresses of 224.0.0.0 through 239.255.255.255 are
set aside through IANA (Internet Assigned Numbers Authority)
as a special class of addresses for Multicast uses.

At the
present, ISPs are unable to allocate Class D address space
to their customers. These addresses must be allocated
through IANA.

Class D addresses are only required if you wish to be a
multicast source. You can still receive multicast data
without the need for a separate Class D address.

TCP/IP Class E Address Overview

The IP
version 4 addresses of 240.0.0.0 to 254.255.255.255 are set
aside by IANA (Internet Assigned Numbers Authority) as
a special class of addresses for experimental and future
use.

The IP
address of 255.255.255.255 broadcasts to all hosts on the
local network and therefore is not to be considered as part
of the E class of IP addresses.

That’s a
wrap for this week. Be sure to check back in next week for
the next article in this series.

In
the meantime, best of luck in your
studies and please feel free to contact me with any
questions on my column and remember,

“The fact
that the grass is greener on the other side of the fence is
directly proportional to how much manure is being used on
the property.”
