I did an nmap scan for my private IP address

nmap -p- 192.168.1.123

and got the following open ports back:

50323/tcp open  unknown
50334/tcp open  unknown
50641/tcp open  unknown
57621/tcp open  unknown
57650/tcp open  unknown
64448/tcp open  unknown

A more detailed scan about those specific ports also didn't yield much.

nmap -p 64448,57650,57621,50641,50334,50323 -A 192.168.1.123

PORT      STATE SERVICE    VERSION
50323/tcp open  unknown
50334/tcp open  unknown
| fingerprint-strings:
|   NULL:
|_    {"type":"Tier1","version":"1.0"}
50641/tcp open  tcpwrapped
57621/tcp open  unknown
57650/tcp open  tcpwrapped
64448/tcp open  tcpwrapped

I'm fairly confident that I'm not responsible for opening them. They're most likely there because Apple uses them for services.

I wanted to know what they do, so I'd know if I should disable them or not for security purposes. However, googling the port names gave nothing. So, I think we should give a short description about each port and the corresponding service, so that others will be easily able to find this information in the future.

There was no option to answer my own question, so note that I'm working on providing the list right now.

Why does Mac OS have many strange ports open and what do they do? 50323, 50334, 50641,57621, 57650, 64448
