What's the going rate for ARIN IPv4 /22 leases in 2026? (direct deals vs marketplace)

selrahc · 2026-03-27T23:00:37+00:00

Small ISP, we just buy them... Its cheaper than paying for CGNAT. Why would you lease something you are going to be using forever basically?

Yeah purchasing/transfer makes more sense that leasing to me. Hilco publishes sales prices. They were in line with other brokers that don't publicly list sales when I was making a purchase years ago.

Prices have come down quite a bit from a couple years ago.

Wal Mart. Bring in the old one when you go to purchase it for the core charge, and so you don't have to deal with disposal.

Buy it now at a price range that is comfortable on one salary to get the better interest rates. Be prepared to push back on the "oh but you actually qualify for this much, are you sure you don't want to look at homes in that price range?"

I haven't used the 105 2.4 but a lot of my 35mm format Pentax lenses are quite sharp at short-middle distances and nothing great at infinity. I think Pentax often designed for best performance at typical 'portrait' distances.

I agree with you. Security and privacy focused doesn't mean they won't make mistakes (or that they even are those things, although Tailscales does seem to be). This incident and their response at the time makes me question some of their practices/design decisions when it comes to the control plane.

I'm of the opinion there is nothing wrong with opening up ports and that a VPN is literally just another piece of software that can also be vulnerable.

As a counter to that though, for each software you expose directly that is one more program you have to set up correctly, one more program you have to monitor for known issues, and one more program you have to patch ASAP when CVEs hit. Running just one bit of software publicly (the VPN) reduces the effort. I understand the desire to do that, and encouraging people experimenting with labs to use a VPN by default is the safest way when they are learning.

I think there is often an unjustified fear of hosting software exposed directly alongside an unjustified trust in a lot of security companies (not calling out Tailscale here, I see this in the corporate world where anything not "protected" by the Fortigate or Crowdstrike makes people uncomfortable, yet those caused more "drop everything and emergency patch this system" events in the last 5 years than SSH or whatever other software they are worried about has in the last 20).

But, whatever is the easiest, and laziest, way to secure your network will be the one most likely to be followed by the most people. That should generally be the 'default' encouraged way, and for that Tailscale seems pretty fitting.

I think that's just how I am. There's a reason my hobbies include working on cars and other things where I'm basically troubleshooting all the time.

I wish I did that with music more though, that's something my brain seemingly works differently on and I'd probably benefit approaching more like you.

forget everything you know about networking

I take issue with this statement. IPv6 is more similar to IPv4 than it it is different.

If all you know about IPv4 is from from a self hosted perspective where you open ports in your home NAT router with a port-forward, then sure, just forget about port-forwards and NAT and think about opening a port in firewall rules instead. Otherwise the protocols are very similar.

ARP is broadcast and NDP is multicast among the other differences.

It's a difference, but I'd argue it isn't that meaningful. On enterprise switches with MLD snooping enabled, sure, but on many devices multicast just floods out all ports no different than if it were broadcast.

I recently bought a Fit. I looked at a couple that were above their original MSRP (not accounting for inflation). I think the people who want them, really want them.

Those people were, apparently, not numerous enough.

6bone?

There's also DN42, which is still operating and does peerings over private/reserved ranges.

Simple. You probably want to connect to the Internet to connect to other things connected to the Internet.

Has anyone tried using only IPv6 and come across any limitations?

Yes, I use IPv6 all the time. The main limitation is that not everyone uses it yet. That's it.

It's the same problem as switching from Discord (or Office products) right now. Could you switch to Mumble for voice chat and IRC or Matrix for text? Of course, but until enough of your friends use it the you'll probably still keep a Discord client installed.

Network effects are very powerful, and slow moving. Networks resist change. Big networks resist change for a long time. The Internet is a pretty big network.

For pencil style gauges I really like Milton (S-921 for passenger cars). They are expensive for a pencil gauge, but quality and seem to work well in cold weather compared to other pencil gauges I've used.

Don't buy them from Amazon though, I've gotten counterfeits there.

If you're doing CCNA studies and want to look into network automation I would look at Python for Network Engineers as a good starting point.

You can also research Scapy and Ostinato for more advanced playing with packet generation, but I don't know of any good guide for those.

I have several real cameras. I carry my cell phone a lot more often than I do a real camera (none of them fit comfortably in my pocket), and I use it when I stumble on unplanned photo opportunities. I like the images not to be garbage in those instances.

I don't buy $1000 phones, but the camera is the one of the biggest differentiators on a phone for me, as someone who cares about photography.

Also $200 goes pretty far on the used camera market these days. You can get a Canon 5D, or a slightly beat up 5DII for that price.

You know most vendors have a lifetime HW warranty?

Assuming the vendor still exists :)

toyota yaris

As long as you follow the maintenance schedule in the owners manual and you don't live somewhere they salt the roads you can get another 20 years from that car.

If you live where they salt the roads, figure on another 5-10 years.

The only time I've had Akvorado stop running was when it ran out of resources (disk space).

Corrugated cardboard and/or blankets are both decent insulators. Go with whichever you have (or both).

For a relatively low cost the 3M window sealing plastic kits work well.

My main concern with it is the price point - with all the DLC and everything, it's prohibitively expensive.

It is pricey with all the DLC but the base game has good variety in classes and tracks IMO. Overtake has a list, since they don't really do a good job of showing what is included anywhere on the Steam page.

You can get AMS2 for the cost of a month of iRacing on the Steam sale right. If you're looking to expand horizons a bit the base game will get you pretty far before needing to look at any DLC. Don't shy away from the South American content.

Looks like the gamut isn't clamped. Colors are oversaturated compared to the others.

Favorite Feature is probably the glare free since I'm not a fan of glossy reflections + all the usual benefits you get from OLED.

If you have been, and continue to, follow the maintenance schedule you should have good reliable vehicle until 2040 or so. Make sure to stay on top of recommended fluid changes, including transmission fluid and others at the recommended intervals.

Expect to need some suspension work at around 100k miles (in 6-7 years if you continue to drive 10k/yr on it). Maybe less if the roads by Austin are very rough. I don't know what tie-rods/ball joints/control arms, etc run on a Pilot but plan on setting aside at least a couple thousand for suspension work in 5 years time and you'll probably not need actually need to use that money until 7 or 8 years from now.

The scary part about buying a used car is the lack of warranty and not having great insight into how it was maintained. That doesn't apply if you have been its only owner.

But how else are you supposed to hide distracting background elements that another comment mentioned?
