Services and port numbers
Example
A simplified FTP connection is used as an example to illustrate how to use
source and destination ports: In addition to source and destination IP address-
es, the IP protocol also uses source and destination port numbers to uniquely
identify data connections. The FTP client creates a number, e.g.
xyz
, which is
used as source port. As destination port, the client uses the number under
which the FTP server offers the FTP service, e.g.
21
. The FTP server then an-
swers with IP packets that use
21
as source port and
xyz
as destination port:
