¿Sabías que Wireshark te muestra el handshake TCP paso a paso?

Cada conexión comienza igual:
1️⃣ SYN
2️⃣ SYN/ACK
3️⃣ ACK

Ese pequeño “baile” asegura que dos dispositivos pueden comunicarse de forma fiable.

Si aprendes a identificar el handshake, entiendes la mitad del tráfico que verás en la vida real.

El mejor truco para estudiar redes sin frustrarse

Solo una cosa:👉 Lee tráfico real desde el primer día.

Ver un “ping”, un SYN, un DNS query, un GET / HTTP… te enseña más que 20 páginas de teoría.

Prueba con capturas simples y verás la diferencia.

¿Qué es ICMP en menos de 30 segundos?

ICMP es el protocolo que permite que los dispositivos se comuniquen para decir:
📍 “Estoy vivo”
📍 “No puedo llegar a ese destino”
📍 “Hay un problema en la red”

Cada vez que haces un ping, estás usando ICMP.

Si estás empezando en redes, entender ICMP te ayudará a diagnosticar problemas reales.
