  • It’ll take you public IP and translate those packets to use your internal one.

    That is NAT, yes. But that is only one small function that a router can perform, and not all routers have NAT enabled. You only need NAT if your ISP only allows you to use a single IP address.

    If your computer has an address that starts with 169, 168, or 10 there is a NAT somewhere in your network.

    That’s not actually true. I can create such a network without connecting it to the internet, no NAT. I can create a second network, again, no NAT. I can then use a gateway router that allows any node on the first network to reach any node on the second. That router is still not doing any NAT. It’s just passing traffic between two networks.


  • Plausible deniability. The real part of the security clearance is the background check they perform, including the interviews. If they find out from some secret source that you immigrated from North Korea, they won’t tell you they figured that out. They’ll just tell you that you didn’t pass the polygraph and send you home. Your North Korean handler will report back that they need to train future spies how to defeat the polygraph, but fail to close the actual hole in their security.


  • Caveat: none of these are formal definitions. This is what I am thinking of when using or hearing these terms.

    I wouldn’t call it an “urban” area unless I can see a privately-owned 4+ story building with an elevator. Government buildings don’t count: they might be the sole example of a 4+ story building within 50 miles. Partial elevator access (intended for handicap compliance to the lower floors) doesn’t count.

    “Suburban” extends from the limits of the urban area, out to where the farms or forests are larger than 100 acres. Suburban areas are primarily comprised of single family homes, but you may also find 1-3 floor apartment complexes.

    “Rural” is anywhere outside of both urban and suburban areas.

    A commercial or mixed commercial/residential area - that isn’t large or congested enough to be considered an “urban” area on its own - would be a “town”. A “rural town” would be a town not connected to a suburban or urban area: you can’t get to a city without passing large farms or forests.

    A town won’t have its own police force. They will rely on the county sheriff’s department for law enforcement activity. Once it is large enough to have its own police, it becomes a “city”.

    In my area, a “village” is a town populated exclusively by people with twice the median income.
