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 and see Wikipedia: 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, IP, and UDP protocols since those are in your list, as well as other OSI Application Layer 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.
