So, installed Wireshark. Ran it, got a few red coloured packets. Used the Expert Infos option on a packet and got this :
Connection reset (RST).
In Wireshark it doesn't have a resolved name for these packets, only an IPV6 address : 2a00:1450:400c:c05::64 or 2a00:1450:400c:c00::5d
I searched and found that you can do an nslookup on an IPV6 address :
Code:
C:\>nslookup 2a00:1450:400c:c00::5d
Serveur : UnKnown
Address: 192.168.1.254
Nom : wg-in-x5d.1e100.net
Address: 2a00:1450:400c:c00::5d
C:\>nslookup 2a00:1450:400c:c05::64
Serveur : UnKnown
Address: 192.168.1.254
Nom : wi-in-x64.1e100.net
Address: 2a00:1450:400c:c05::64
Turns out, it belongs to Google :
