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:
- 10.0.0.0 to 10.255.255.255
- 169.254.0.0 to 169.254.255.255: used by APIPA only
- 172.16.0.0 to 172.31.255.255
- 192.168.0.0 to 192.168.255.255
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
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.
