Do hosts have a physical location or not?
In this edition it seem as if you have three different types of hosts.
- Virtual matrix hosts (think 'cloud') that does not have a physical location and you always have zero distance to (think SR5 hosts). For inspiration how this could work you can google old 2020 technology such as 'Mesh networking' and 'Distributed computing'
- Physical hosts (think 'on prem') that is perhaps located inside a facility they are protecting. Distance to the facility (or nearest access point) matters
- Offline hosts (think 'air gap') that you need to directly connect to. Distance is always zero once you connect, but you first need to physically travel to it. This is basically the same as a physical host, just that there are no wireless enabled access points to it.
When and where and which you consider being the most common is up to each table.
Personally I will reserve virtual hosts for governments and larger corporations etc. At my table, most hosts that shadowrunners will interact with will be physical hosts (for example residential buildings, factories, local libraries, local police precinct, office buildings, local clubs, local stores etc). I will use offline hosts for paranoid societies, research facilities, hardwired underground military facilities etc.
Of course if you retcon out techno souls, then you must rely on physical network architecture. Routers, switches, cables, and firewalls are all physical.
It seem as if routers and switches and VLANs etc we use today are represented by nestled networks.
Offline networks obvious need to rely on cables, but most other networks will mostly (or even exclusively) use wifi.
Firewalls seem to be represented by the firewall rating of the network.
Note that no matter which type of network we are talking about, once you are inside the network - you are inside.
Type of Host only matters when it comes to how to actually access it (and if you need to consider distance or not).
Once you access it you will use the same matrix actions as you would against any of the other Host 'types'.
So if you want to hack your corner stuffer shack, it's almost guaranteed that its particular host is not running off a server somewhere on its premises...
As I see it;
Even if the physical host is not located inside the facility it is protecting (personally I think it will be most common that it is located on prem, but anyway) a physical host can also have 'access points' at various locations where it make sense from a connectivity point of view (one physical host can probably be used to defend multiple buildings and as long as each building have access points to the network you will be considered to have no distance to the host as long as you are within any of the buildings). If the physical host is located in japan then it will also most likely have a few local access points inside Grampa Olaf's Liquor store (for example I'd imagine that the camera behind the counter, the maglock at the front door, the light switch controlling the lights, the sprinkler system and the two vending machines are probably all acting as local access points for the host they are part of).
"Still ... access points exist, so that people across the globe can log on whever(sic) they want."
