When you access example.com, you see a generic site tells g you this is my Domain and used for some personal projects. On it is a link to blog.example.com (obviously a blog) and other public services like search.example.com (being a searxng instance).
Also not all are hosted on the same server and some subdomains point to other IPs. For some services I do have another domain, but in general, they're just grouped with some logic.
Not sure what a reverse proxy would offer me here...
Are those "real" pistols, or air pistols? Because the latter should make you deaf. So.eone else commented, they'd not use it for protection but to focus and reduce distractions from the audience and other sounds
Well, VDSL and VDSL2 use 138kHz to 12MHz and then 30-35.5MHz (according to the german Wikipedia - I couldn't find that table in the English article.)
Powerline has several standards (same as above, couldn't find that table in the English Wikipedia), but the frequency range starts at 2-4MHz and ends at 20-30MHz (with one standard using 30-68MHz).
For DSL, there's not really a problem using these frequencies but powerline transmits at a higher power and intentionally uses cross talk as a feature. The byproduct is that now your power cables act as an antenna and the Powerline signal "leaks".
Medium Frequency radio stations e.g. use the band from about 520kHz to 1.6MHz which correlates with Powerline and can be affected by it.
Edit: Medium Frequency transmissions in general (300kHz - 3MHz) and High Frequency transmissions (3MHz - 30MHz) can be affected, but radio stations shouldn't (~530kHz - 1.6MHz).
And yes, if you're transmitting "strong enough" over Powerline (depending on your adapter and how well your cables act as an antenna) one could recieve your signal and decode it. IIRC the signal is encrypted (somewhat like WiFi - the adapters need to be paired to talk to each other), but I don't know much details about it.
Just beware, if you’re in a place where you can only get DSL and coax or fiber are not available - Powerline does use the same frequencies as DSL and both the power cables and your landline are unshielded wires. So there will be cross talk and powerline can and probably will affect your DSL connection. Also depending on your cables and the powerline adapters you use, you may disturb radio stations in a wider area around your house.
Are there any cast-delays or such? Otherwise, you could just say I cast, as soon as they're 30ft away
