TCP & UDP well-known port reference for C# and Visual Basic .NET (VB.NET)
Below is a list of well-known TCP and UDP ports used by everyday applications and services.
Some of these ports are known to be used by viruses, and thus detection of heavy or regular pulses of
traffic on these ports can indicate infected machines on a network. To find further information on
common protocols, or read about ways of detecting such traffic on a network, the book Network programming in .NET
should be of invaluable assistance.
