Which port is commonly used by the Network Time Protocol (NTP)?

Explanation:
NTP time synchronization uses UDP because it’s a lightweight protocol that sends small time updates with low overhead. The standard and widely used port for NTP is 123, so traffic related to time sync is expected on that port. When you see other common services, you’ll find DNS typically uses UDP on port 53, SNMP commonly uses 161, and SSH uses 22, which is why those ports don’t apply to NTP.
