Dynamic and/or private ports: 49152–65535

By definition, no ports can be registered in the dynamic range.^[1]

Many Linux kernels and/or distros use 32768 to 61000. /proc/sys/net/ipv4/ip_local_port_range indicates the range in use.

Registered ports: 1024–49151

1024–49151



Only those ports that are commonly used are listed; for full list, refer to the IANA port list.[1]



When investigating TCP traffic, be careful not to confuse the client and server ports. The client port is incremental, typically beginning at 1024 at boot time and wrapping at 4096. If the port you are investigating is in the lower part of this range, it may be a client port. Stateful firewalls identify the server port, but packet sniffers and stateless firewalls do not. For example, a packet sniffer showing a TCP packet with source port 1080 and destination port 1494 might be either the SOCKetS or Citrix Independent Computing Architecture (ICA) protocols. The only way to know for sure is to examine the initial TCP handshake.



With UDP, client port selection depends on the application and may be incremental, fixed to a nonsensical value, or fixed equal to the server port.
