Recently, I've had to look for alternatives, as I was forced to 'upgrade' to fiber by my ISP. As a result, I've been put behind carrier grade NAT, which means that I no longer can get incoming connections to my servers. I would be forced to either get a static IP (with an accompanying business plan for mucho dollars) or switch carriers (which I'm investigating as I type this).
In the meantime, I ran across the MixCloud service, out of Britain (which fits in nicely with my boycott of U.S. businesses). The service allows you to post a limited number of radio shows or podcasts for free, and you can upgrade to their Pro service which promises unlimited uploads. The nice thing about it is that they claim to pay all music royalties. I know others who are using MixCloud with great results.
I've posted one of my Teenage Dreams shows as a test - Teenage Dreams #63 - Baby.
Depending on how this is received, I may post more while my search for a new ISP continues.
You know, my sole internet connection for at least the past 5 or 6 years has been cellular wifi. Have you considered just getting a sim card router and using T-Mobile or Verizon or whoever?
The cellular carriers may or may not be using carrier grade NAT (essentially a network within a network - your public IP address is mapped internally within their network, and you do not have capability of port forwarding.
Until I was forced to migrate to fiber, the Telus copper network worked fine on regular old NAT.
Good luck finding anyone in customer support for any ISP who understands these concepts. If you have a home security system, or camera, with carrier grade NAT you no longer have the capability of going in and monitoring it.
There are software workarounds, but they tend to get very complicated, and rely on outgoing connections (which still work) to shared servers elsewhere, or even Cloudflare tunnels. But there's still a cost associated with these solutions, and you're also opening up your own network to the outside (which I'm not willing to do).
The way to go is to get a static IP (if you're going to host your own server), and there are still ISP's with reasonably priced offerings who will sell them. IPv6 was supposed to resolve the limitations of IPv4, with limited numbers of IP addresses, but many ISP's and websites don't support it. My ISP does, but it still does some network mapping on the public IPv6 address, so that you can't port forward.
In the meantime, I'll see how MixCloud goes. It may end up being the cheapest and most convenient way overall, even with the unlimited, paid subscription.
