Hello,

I am working on sth where I need the port numbers being used by different applications and/or protocols. I have listed the applications and the protocols so that you can send me the ports being used by each one(s).

Also, please add if I have missed any applications and protocols if necessary

1. HTTP = Port Number
2. HTTPS =
3. POP
4. POP3
5. SMTP
6. IMAP
7. Yahoo Messenger =
8. Hotmail Messenger =
9. UDP =
10. TCP/IP =
11. Active Directory ? Which protocol Active Directory uses (TCP/IP or LDAP?)

Regards,

You're lacking a few. Here's the official list (http://www.iana.org/assignments/port-numbers) and see Wikipedia: Port numbers (http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers). For things not listed just Google for "[application] ports" such as "Yahoo messenger ports". Ports may change on the whim of the vendor.

You may also want to read up on the TCP (http://en.wikipedia.org/wiki/Transmission_Control_Protocol), IP (http://en.wikipedia.org/wiki/Internet_Protocol), and UDP (http://en.wikipedia.org/wiki/User_Datagram_Protocol) protocols since those are in your list, as well as other OSI Application Layer (http://en.wikipedia.org/wiki/List_of_network_protocols#Layer_7_protocols_.28App lication_Layer.29) protocols.

Active Directory is also an overall picture for many things. Within AD, you have many functions which use protocols such as DHCP, DNS, WINS, Kerberos, etc.

TCP/IP is a stack of utilities. Within this set of utilities, each communicates over IP with a specific protocol or group of protocols. Each port can have a TCP or UDP associated with it.

The first 1024 ports are standardized and the "high ports" are used as required by vendors and users alike.
