Do I have anyone within my reach who would be willing to help me debug a DNAT issue on OPNsense?
I can sincerely say that it's *probably* trivial, and I am *probably* just missing something obvious; but it's not obvious when you're not quite sure what you're looking for. Reading the documentation, browsing the forum and searching the web has not led me to find a solution.
Boosts appreciated.

Is there a standardised (or vaguely common) hostname akin to localhost that either a) only resolves to the IPv4 127.0.0.1, or only resolves to the IPv6 [::1]? In my experience, whether localhost resolves to an IPv4 or IPv6 address seems to be somewhat OS-dependent (or even system-dependent), I am wondering if there's a standard way to specify that I do want either the IPv4 version or the IPv6 version?
Why, you ask? I have a service on localhost that only listens on IPv4, but today localhost resolved to [::1] and it broke. Now I fixed it easily by specifying 127.0.0.1 as the server address instead of localhost in the upstream proxy, but it did make me start wondering.
@goldfishlaser thanks! I am always on the lookout for any decentralizing technologies.
This #meshtastic looks good, but I'm primarily interested in such platforms or networks which can handle #tcpip or #ipfs .
@nonfedimemes Seeing the mention of carrier pigeons has me think that sure, any step towards an independent, interoperable RFC1149 implementation would be welcome (see https://www.bsdly.net/~peter/rfc1149_ten_years_of_in-flight_internet.html for some relevant links), but that would perhaps run the risk of being somewhat distruptive in a school or at least classroom environment #rfc1149 #pigeons #tcpip #cpip
If you're not running your own DNS resolver, and/or not running PiHole, changing your DNS from 8.8.8.8 to 9.9.9.9 is a good first step 
Blast from the past: I digitized and uploaded a 1993 VHS video tape that was included with my trainer kit for teaching Internetworking with Microsoft Windows NT 3.5.
I assume the audience for this one is pretty niche, but for me it provided a welcome dose of healthy nostalgia.

Friends, I have a problem with the ISP that operates the fiber line to our house.
Pretty much every time they need to reconfigure their CGNAT they for some reason kill IPv6 and our autoconfig'd gear end up with "Unique Local" (fc/7) addresses.
Is this a common problem, seen elsewhere?
I suspect Cisco gear but have no way to check.
