Me gusta esta pregunta nmap muestra IP desconocidas desde 192.168.2. * en mi red doméstica que tiene un rango de IP de 192.168.1. *.
A diferencia de la pregunta anterior, cada IP parece estar completamente bloqueada, incluido el bloqueo de los intentos de ping. Para todas las IP (alrededor de 70 entre 192.168.2.0 y 192.168.2.143), la ejecución de nmap -A -Pn da como resultado:

Llamé a mi ISP en base a la pregunta vinculada anteriormente, y dijeron que no era su equipo.
Soy nuevo en administración de redes, pero he desarrollado software durante 20 años, por lo que estoy técnicamente interesado. No estoy seguro si alguno de los siguientes podría ser la causa.
- VMWare se instaló hace años, pero nunca se usó realmente.
- MS HyperV con un interruptor virtual, sin embargo, todo en ese interruptor es 192.168.1. *
¿Alguien tiene alguna idea?
