(Fedora-42; stand-alone workstation)
This is a totally new Fedora install on a stand-alone workstation, done
today. It is not a part of a LAN or WAN or any other home or office
network.
Please describe how the system is connected to the internet. Does your
system get an IPv4 address
or IPv6?
unsure. I'll continue through this thread and see.
Many "home" internet connection hardware does network address
translation (NAT) to a non-routable
address used by attached devices <https://en.wikipedia.org/wiki/
Network_address_translation <https://en.wikipedia.org/wiki/
Network_address_translation>>.
Vendors support NAT because it allows one IPv4 address to be used by all
the devices on each
customer network, but it also prevents external sites from connecting to
the devices on the
customer network.
With NAT, connections to external systems must be initiated from your
system, but many web sites
use multiple external sites for elements of the page you see. There is
always a risk that one of these
sites has been hacked and is serving malware or stealing personal
information. Firefox on Fedora
includes some measures to block or mitigate such attacks.
