IP Networking

IP or Internet Protocol Networking is a large subject, so here I am only going to cover some stuff and link to the rest.

Reserved IP Addresses

There are a couple of reserved IPv4 address ranges as follows:

  • to - reserved for private networks
  • to - reserved for loopback
  • to - used by APIPA only
  • to
  • to

Further details are available on Wikipedia at Reserved IP addresses, however it is also worth considering that the ranges listed above are mostly used for Private network.

Reserved Ports

For a list of commonly allocated port number for use with TCP/IP List of TCP and UDP port numbers - Wikipedia, the free encyclopedia is a good reference.

Subnet Ranges

There is a handy calculator at IP Subnet Calculator.
