- a self hosted dropbox
- a phone that does not send data to google or apple without my consent, and where I can be absolutely sure it does not
- a self hosted sync server for my phone (contacts and calendar)
- a very fast internet connection to my home (I self host almost everything...)
that's it. I am sure once I have those I will need more :)
For bandwidth, would you consider hosting stuff on a VPS with better upstream bandwidth, or is that not enough control for you?
1) In my area a static IP is extremely expensive and outside of my budget. This leaves Dynamic DNS.
2) From what I can tell, Dynamic DNS providers only map 1 domain to your account. I would like the ability point more than 1 domain to my personal server. Can I do this without paying through the nose?
You host a box via DynDNS and its canonical hostname is, say, "mystatichost.example.com".
You decide you want to run a www and an ftp on that domain: CNAME www.example.com and ftp.example.com to mystatichost.example.com. 'www.example.com' is your default host on that server.
You decide that you want several entirely different domains, say, example.net, example.edu, and example.org, all running from the same host. You'd again point CNAMES to 'mystatichost.example.com', and on your httpd config, create named virtual hosts for those domains. So long as the http request is for 'example.org' and not 'example.com', the surfer won't know the difference.
That's been a part of basic webservers (apache, nginx, etc.) for, oh, well over a decade.
Mail/MX can be handled similarly. Your domains' MX records point to 'mystatichost.example.com' as their mailserver. That's how every mail hosting provider in existance does this (say: googlemail.com for anyone using GMail hosted domains). There's absolutely no reason the end-user would know the difference.
Again: all very basic Internet plumbing basics.
