24 Ago 10 Why do not host sites from your own home

I would not recommend you to host sites that way, you have to be sure that your ISP give you public IP(s) and setup your router to port forward ports 80, 443, 53, and so on.
There are other problems too:
1) if you want to host more than one site with SSL you must have one public IP for each SSL site or use different SSL ports for each site, because name virtualhosting with SSL is not possible;
2) dsl lines are not designed to be stable. The connection can go down and make your site not visible. This is a major problem if you make the mistake to have your own DNS server on it!! The ISP assigned public IP address can change more than one time a day and you have to sync the DNS zone each time.
3) dsl ips are putted into DNS based blacklists zones. You may not be reached from various HTTP proxy servers around the world. For the same reason you cannot send mails, for example originated from your sites.
4) adsl lines are asymmetric (unbalanced for download). You have few kbytes per second in upload, that is just what you need to publish web sites, so this can be a problem when you have just more than 3 users.
5) you probably have problems with High-Availability and Load-Balancing on domestic hardware and you may have blackouts.
6) DNS subsystem may need primary and secondary DNS servers.

The best way (imho) is to use services like slicehost where you have a HA virtual server slice running linux, public IP addresses, free primary and secondary DNS hosting service, large public bandwidth, disk space… and not last your own root password that you can use to have maintenance on your own server for your own.
