I've seen things about this, but I'm not convinced there's enough value in going to great lengths to replace that particular piece of equipment. In the case where the terminating equipment is a small box that exposes ethernet, with no routing or otherwise interfering the function of my own router, I think it's good enough. An argument could be made for the all-in-one devices, like saving some power. I get the geek fa…

For me the issue would be that they mandate the user traffic to be vlan tagged but their modem only exports 1000BASE-T so it's physically impossible for me to get the full gigabit of Internet they sold me.

They most probably sold you 'up to 1 Gb' bandwidth, not just '1 Gb'. Overhead is about the same in these cases. Your losses are negligible. It's more painful having 4-5 (on worst time periods/peers) or 6-7 (on best) of the 'up to 10 Gb' (clearly sold as such) fiber access I have.

How does it work in Germany?

Your by law allowed to chose your own hardware.

And do they exert any control over the software and configuration on it? That was kinda the crux of it after all.

You may either rent/buy a device from your ISP, or you may bring your own, at your discretion. ISPs are required to accept all devices, of course if your device kills the network segment, they will kill your connectivity. But they can't refuse to let you connect.

What happens if your device connects 1000 volts to the cable and fries everyone else's device and the head-end?

Peering has everything to do with the physical interconnect and nothing to do with the ID numbers used to describe that interconnect, IMO.

Then we are just talking about two different things. On ISP level, routing tables are built via BGP. BGP needs Autonomous Systems (AS) as organization unit to work. If you are not an AS you are never a peer as you are not on equal footing. As a rule of thumb, if your edge router has a default route set, we are very likely talking about different scales.

ISPs are encouraged to — but rarely do — use private ASNs with single–homed BGP customers.

> providers install their own Glass Fiber modem It's the same in the US. The ISP fiber network falls inside their security boundary in my experience - you can't BYOD. They install a modem (these days often including an integrated router, switch, and AP) and you receive either ethernet or wifi from them. I think the only major change in that regard has been that coaxial cable providers here will often let you bring yo…

US ftth in my experience (att + gfiber) are ONT and router/wap as separate boxes and you are free to byo routerbox but have to use their ONT.

Supposedly some of the major US providers (at least AT&T) have dropped a bunch of the obnoxious, ineffectual security stuff in the XGS-PON networks. There are plenty of reports online of people quite successfully running an entirely third-party stacks using adorable SFP+-format ONTs without anything that would credibly be called hacking.

Is it possible to use a media converter from glass fiber to RJ45/Ethernet? Those are commonly available and then you can use whatever modem/router you like.

I don't know if it's the case in Germany, but here in France consumer FTTH networks are of the GPON persuasion. These need to handle encryption and be able to properly register on the tree, so I'm not completely shocked they require some form of ISP-provided device to terminate the fiber connection. There's also a EU law which says that users should be able to bring their own modems / routers, so AFAIK providers say…

Can confirm you can still replace the ISP provided router from SFR with your own, even if you're on IPv4 CGNAT in France. You do still need to configure the DHCP client ID.

My connection has been very reliable since ditching the SFR box. My own router plugs into the separate ONT.

SFR also offers good IPv6 support.

Slovenian ISP T-2.net also violates local network neutrality laws here by requiring customers to pay extra to unblock some special TCP ports, like 25 and 53, meaning they block selfhosting email and dns servers without additional payment. I filed a complaint to the national regulator AKOS. They first responded with agreeing with me, but nothing was fixed for many months, and upon emailing the regulator again, I recei…

Calling this "paying to unlock ports" is disingenuous. I'm also a T-2 customer and have run into this before. They block ports on dynamic IPs, but if you pay +2€/mo for static, this is unlocked. This seems reasonable. If you're not paying for static IPv4, you're paying for "internet access", whether that's a rarely chaning dynamic IPv4, a constantly changing IPv4 or full CGNAT. Would you also say your mobile phone op…

Why does that seem reasonable to you? Why should dynamic IPs not be able to receive incoming connections? It costs them nothing to let those packets through.

> disingenuous

Bad.

> Would you also say your mobile phone operator is violating net neutrality by putting you behind CGNAT that you can't forward arbitrary ports through?

CGNAT is pretty awful, but at least there's a reason for connections to fail.

But sure, if I had control I would mandate that CGNAT lets you forward ports. Maybe you don't always control the external port, but there shouldn't be any other compromises.

> You can pay a bunch of money to get a private APN and get public IPv4 addresses. Would you call that an unblock fee?

That's a workaround to get a different connection, not an unblock, so no.

Isn't that fairly common? You could then put in some other address, but you could do the same thing by setting up your own mail server, and in the former case you're not even really anonymous because the headers are going to show it was sent through their mail server and their mail server's logs will show which account was used to send the message.

The email sent from your own separate server will fail basic dmarc/SPF/dkim validation the email sent by their own servers likely will appear legitimate

It would fail in the same ways unless the from address you're using is on their domains, which is then only a problem for their own customers rather than innocent third parties, and their own customers have the sensible option to stop using their service.

The best solution here would probably be the EU launching its own internet constellation. China and the US both have them. How is this any different than the issues surrounding GPS?

The EU did do that, decades ago. The problem is that it requires constant investment. It's not profitable. The governments helped build it, abandoned the companies until they went bankrupt, rescued them (they're not actually insane enough to just abandon working satellites), privatized them, they went bankrupt, ... Obviously the satellites were never modernized. But it does work, for a few thousand terminals for all…

> If you calculate the lifespan and cost of a Starlink satellite you will come to the obvious conclusion: it will be very hard for Starlink to break even.

We don't have up to date revenue numbers but let's look at spending $5B a year on sattelite launches. That's probably around half their current revenue, and they're gaining customers quickly. They're doing about 100 launches a year, and each launch is about 30 $1M satellites and $15M of rocket. That fits into the budget.

And for just maintaining the constellation they could cut the number of launches in half.

Telekom is a bunch of strange folks. I lately was not able to send mails, from my private mail servrr to my fathers telekom mail. After investigation I found out my server got blocked. After a decade of working. I mailed them, and they told me to register my mailserver with them. I shall tell them what mails I will send from there and about what content. I couldn’t believe my eyes. Sure, thats how mail was supposed t…

Does anyone self host email anymore successfully? I'm honestly asking. I would like to but it seems like a full time job trying to keep it running. Are there halfway solutions where maybe you own the service and domain and it runs somewhere trusted?

I've been self-hosting my email for a little over 2 decades.

The basic setup has more or less stayed the same, but there's some more extra components around it you have to know now (spam filtering and SPF/DKIM/DMARC come readily to mind).

To quote Michael Lucas: "everything complicated about emails revolves around spam and not getting it". I highly recommend his book, "Run Your Own Mail Server".[1]

In short, hosting your own email is not that bad at all. I strongly suspect, like many other skills, since it has atrophied with the advent of the cloud and people readily giving up to the large carriers, it has gotten the reputation of being hard, or as you said, a full time job. I don't think either of those things are true.
