I've often wondered how much of the IPv4 address space is legacy allocations that are not at all being fully utilized. Perhaps the market for IPv4 addresses has worked this out, and anyone that has such an allocation has cashed in.

For enough dollars you can sample 100k address at random and have a decent guess? Not everyone responds to a ping but I suspect most do

For 0 dollars, you can get a BGP table dump and see how many addresses aren't even routable. (doesn't mean they're not in use, but makes it less likely)

This reminds me of a conversation I had with the AC repairman last year. Backstory: we have an old AC unit that uses freon. The repairman mentioned that freon is no longer available for new AC units. I asked if you could still buy freon and he said yes, existing supplies were grandfathered in. I then commented that the price of freon must have sky-rocketed and he said: "yes, it did for a while but then it became chea…

There's an initiative in Guatemala where land owners are paid an amount of money every year for each acre of their land that they reforest.

Naturally, land owners immediately started clear-cutting virgin rainforest, selling the lumber, and then collecting a payout from the government for planting pine trees that they'll raise for 10 years before they'll cut them down for lumber too.

ICMP is blocked by default now in many firewall setups, so unless the admin specifically allows ICMP the packets will likely be dropped. Also, be careful as "host discovery" can be viewed as a type of "hacking" depending on who you are and who is watching/judging you.

Your first point is definitely correct. Your second point though... really? Do you have any sources for anyone, anywhere being charged for using ping?

No, I haven't heard of anyone being criminally charged for ping, but I have known someone whose ISP cut them off and he had to go through an onerous process to get service restored. I've also heard of people that use EC2 instances and get their AWS account terminated.

One thing that is annoying is that ARIN recently raised the amount of money it costs to maintain a /24. I was unexpectedly hit with a $500 bill when previous prices were $100. Was quite annoying considering is very little cost in providing these allocations (they really beef up their headcount). Been thinking about trying to get on the board but it is near impossible.

I had an 88 Chevy Pickup Truck that used the old style freon (R12). Man that stuff worked so good. In 100 degree heat that truck would stay nice and cold. It took over 20 years before the alternatives were competitive.

Propane makes a good substitute for R12 with very little modifications. I wouldn't use it inside a home or anything like that, but I have used it to make older vehicles blow cold. It's extremely good refrigerant. The biggest problem people have is that it ends up too cold and icing up the system. It sounds dangerous, but it's really not. Propane is only flammable with the correct mixture of air. Otherwise you couldn'…

This might be the most amazing and interesting comment I've ever seen. Thank you :-)

What you say makes good sense too since many RVs have propane refrigerators. I've long wondered how it works exactly. Probably time for a DuckDuckGo search.

Propane fridges actually burn the propane for heat, so it's not using it as a "refrigerant", just as a heat source.

Would a propane tank pose any danger to occupants during/after an accident?

A scheme in Northern Ireland (colloquially known as "Cash for Ash") was set up where heating properties using renewable fuels (mainly biomass) was subsidised, only the subsidy was priced higher than the cost for fuel causing people to heat empty properties just to claim the subsidy. The whole thing cost almost half a billion pounds.

There have been huge allegations of fraud and it even brought down NI's power-sharing executive (~ the regional government) in 2017.

I once applied for a position at what I found out to be a spam marketing company. In order to send their spam they worked with a local hosting company that would take unused legacy ip addresses and put them in their router so the spam could be sent over them. They would just burn the ip's and move on to the next set. My job would be to update their firewall with the new ips, update their mailing software with the current set of ip's each day. They made their own mailing software it had an interface like a stoplight where red meant the mail wasn't going out, yellow a lot of it was getting blocked (so move to the next ip's) and green is things are good. I didn't end up taking the position. This was around 12 years ago.
