Hi /wsr/, I'm using a modem/router not provided from my ISP and need to configure my access to the IPv6 network. Sadly these idiots from support have zero idea and can't give me any information.

Their own router does support IPv6 and they give me an address over 6rd, but I don't find anywhere online the IP address of their border relay gateway.

I need the IP or domain name for the ISP "Sunrise" from Switzerland.
Google just finds me the address for Swisscom and Wingo ( 6rd,swisscom,com and 6rd,wingo,ch ).

Is it possible to sniff out that IP with Wireshark? If yes, how should I sniff it with Wireshark?

Thanks
