samsung.com - Packetloss 100.0% #70

Great library! Is there any reason why samsung.com (and I assume, other websites) do not work while google.com is fine?

It seems to point to the redirect to the IP and fail (211.45.27.231).

Hi @sabatale,

Thank you for using this library! It seems indeed 211.45.27.231 does not respond to ICMP Echo Request. This is not related to icmplib, any other tool (like your system's ping command) is also affected for this destination.

I guess Samsung has to block these requests with a firewall (or else, there is nothing behind this IP address: it does not respond in HTTP either). Unfortunately, there is nothing you can do on your side.

If you really want to check the accessibility of this destination, use the FQDN www.samsung.com that answers instead.
