Does that mean it is an RFC1918, and that the modem does do NAT and the firewall? Am I understanding Louis correctly? What's the practical significance of this? You are a Comcast customer. Comcast owns 67.172.0.0 - 67.172.255.255 So, your IPv4 address is also a Public IP address the same way the IPv6 address is. Directly connected to the Internet with no NAT. Also, your modem does not have an internal Firewall. Therefore, the firewall on your system is vital. -- The key to getting good answers is to ask good questions. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
