Yeah. The number of things we use in everyday life which would not have occurred to The Authors to consider as a "computing device" is mind-blowing. I seriously wouldn't be surprised if the number of addresses used just by my own company exceeds the total envelope of IPv4. It was kind of a point of pride back when I worked at Harris that we used real world IP addresses for even the most trivial shit. Harris was early to the party, and it made life SO much easier. |

One of my prized possessions is his autograph on a copy of RFC1149 (aka, IP over Pigeon).
And I love the fact that The Unlimited actually implemented it in real life. (And it beat the landline it was competing against in throughput, though obviously not in ping times.) |

It's not so much of a concern anymore, because of NAT (Network Address Translation). In the IP Address Space world, there are a few specific network (192.168.X.X, as the prime example) which are designated as private.
There are actually large cloud companies who have used up all of the RFC 1918 space allocation (192.168/16, 10/8, etc) on their internal data center networks, to the point that they run their routers with IPv6-only addressing and require extensions to the routing protocols to allow IPv4 routes to point to IPv6 nexthop addresses. --Ian |
I was doing my best to give the "drink from the hose" example, rather than the "Here's the firehose to the face example."
You are entirely correct, Ian. |
fwiw: Amazon is selling gallon jugs of Rotella T6 5/40 for $22 with $1.50 coupon and $7 rebate- free ship with prime.

when i worked at hewlett packard, they owned the 15 and the 16 net (which they got from digital equipment corporation via compaq). addresses galore.

what are the private ipv6 addresses? |

what are the private ipv6 addresses? Some say that it's fc00::/7 as per RFC4193. Others say that has been deprecated (that fc00 is reserved for future allocation) and that fd00::/8 should be used instead. Both of these spaces, however, are technically routable. If you want truly non-routable addresses (eg: total isolation, or whatever they call NAT these days), that's fe80::/10, which is specifically called out as a link-local range in RFC4291. |

Link-local addresses really aren't the same thing. --Ian |
So, I had a visit from Verizon today. I was expecting one engineer and maybe one manager. Instead, I had like half the local corporate office show up (20+ people), and spent four hours this morning giving them a tour of the facilities. I could tell that half of these people had never been in a machine room before. Kept having to say things like "Pay attention to what's behind you, there's 480vdc on that conductor, and it will kill you if your butt touches it."
They want to trench from the street into my building and give me 100 Gb worth of fiber. And they're paying for it. I'm naturally suspicious.... |

Gents, I went ahead and got myself a TIG welder...
Looked into a bunch of entry level units and asked for advice from professionals. Long story short, I ended up acquiring this: https://cimg7.ibsrv.net/gimg/www.mia...34029386e8.jpg Came complete with a bottle of Argon, regulator, connectors, torch, and spare tungsten electrodes. I also bought a nifty auto darkening helmet. It is a pretty impressive machine - I can even stick weld with it if I need to. Can weld aluminum, stainless, unobtanium, sheets of cardboard and ice. Got my first "crash course" from the owner of the shop my car currently resides in for my turbo manifold, DP, exhaust and other related fab work. He showed me some pretty neat tricks and tips. I will be signing up for certification courses offered by Oerlikon and attend whatever training program I can get a hold of. Successfully completed my first joining task, welding two pieces of 3" stainless exhaust pieces, and it was very satisfying. I am excite. |

Congrats, GodlessCommie. I am excite for you.
I used my mig welder just last week and was reminded how much I want it to be a Tig welder. |

They're making you an offer you can't refuse.
When AT&T did this about 6 years ago, they just piggybacked onto an existing data circuit. Verizon doesn't have an existing circuit into our building, so they need to pull in a new fiber. They're doing this on their dime (we buy a LOT of cellular service) and they probably have a good estimate of how much landline bandwidth we use in total, so I guess it makes sense for them to just go ahead and pull in the biggest circuit they can, so that a year from now they can say "Hey, you need a 10 gig dedicated connection to some random location in Indiana? As you may know, we already have more than sufficient capacity in your building, so it'll cost you nothing to set up."

That process did, in fact, look like the scene from ET. Lots of plastic sheeting, lots of air ducting, and men in bunny suits coming and going constantly. This will just be a couple of work crews with one of those cool horizontal drill trucks. |
Also a PSA:
Please do not lick the dolphins. Thank you. |

That brings back memories. I basically rewired our lathe and plaster 1925 home that way. Same for the home audio and security system. Found all the absurd lumber nailed into to bizarre places. Also found out the second floor burned at one point and learned "clean up" did not include all the ashes.
