PoE sends power and data through a single Ethernet cable, making it easier to connect devices like IP cameras, VoIP phones, and sensors. No PoE switch? An injector adds power to the cable, while a splitter separates the power and data for devices that don’t support PoE.

Here are different types of PoE configurations 😎👇

DNS looks simple: type a domain name, get an IP address

But behind the scenes, it’s a distributed lookup system. No single server knows every domain. Instead, your request is passed through a hierarchy of name servers until it reaches the authoritative server responsible for that domain 😎👇

Wireshark filters cut through the noise so you can focus on the traffic that matters.

For blue teams, they help track suspicious activity and investigate forensic evidence.
For red teams, they help map behavior, spot weak points, and test defenses during pentests.

Here are useful Wireshark filter examples 😎👇
