Comment on ISPs seem designed to funnel people to capitalist cloud services
ellie@slrpnk.net 3 weeks agoEven in an ideal DNS setup, you’re probably going to have downtimes whenever your dynamic IP changes. If only because some ISPs even force-disconnect you after a while to change your address.

I mean I’ll be real. Sure in some circumstances that could be an annoyance for 15 seconds for some software that might rely on a session whenever your ip changes like once a month if that. A rotating ip is probably one of the easiest things to work around amongst the plethora of challenges that ISPs present for those who want to self host.
I mean just take a look at what is involved if you are in a situation where cg-nat is implemented. You legitimately have no control over the root of your network at that point. I have that issue in particular with what is essentially a mobile hotspot as my failover for when my fiber fails. That being said I had to architect it in a way that took that took cg-nat into consideration. If I hadn’t then when fiber fails it would take down my services as a whole anyway.
My point is that those challenges have workarounds, you can solve those issues relatively easily and they even present a level of security. Where it is actively malicious is with restrictions to capacity such as upload limits in which they to a degree lie about their speeds and capacity. The terms of service stuff is just flat out awful too.

Some ISPs require changes ever 24 hours and will disconnect you if needed. Also, if you set DNS to cache so little that you can react to that in 5 minutes, you will incur way more DNS traffic which can become a problem when your site is busier.

What ISP are you referring to? I have genuinely never heard of an isp that takes 24 hours to rotate your IP. Also utilizing dynamicdns is not going to incur more dns traffic? Dynamic DNS updates your dns provider from a system on your local network that your pub ip has changed then your provider will start sending traffic to the new ip. Propagation used to take a while but I haven’t experienced propagation wait times of over 10 minutes in years. This all being said dynamic DNS isn’t exactly the most elegant solution. It is just one of the simplest that I mentioned. There are significantly better options overall that completely take the requirement of a static pubip completely out of the equation and can be built using all free open source tools relatively easily.

It causes way more traffic for the DNS server to use a shorter TTL, so yes, it does incur more DNS traffic. In Germany some providers will disconnect you regularly if you stay connected for too long.
