Time and Naming Services

Beyond moving packets, networks rely on background services that keep everything consistent and usable. Two of the most fundamental are time synchronization and name resolution.

Without accurate time, logs and security break; without name resolution, users would have to memorize IP addresses. These quiet services underpin nearly everything else on the network.

Computers need synchronized clocks for many reasons: log entries across devices must line up to investigate incidents, security certificates have valid time windows, and authentication systems like Kerberos reject requests if clocks drift too far apart.

Even a few minutes of clock skew can break logins, scramble troubleshooting, and cause hard-to-diagnose failures across an entire network.
