Because of my hosting provider, you are able to read this site (and almost all of my sites). I had the company I used since 2002, and have a plan that is no longer available. I am glad that I am able to keep my plan since it gives me unlimited domains, and subdomains?, and anyone visiting my Domains Page, you would see why I will need unlimited subdomains, and unlimited domains?. With that in mind, hosting these sites are important to me, and I will continue with the hosting plan as long as it remains affordable. My only other option would be to find a reseller package, and pay whatever fee I will need for them.
The hosting provider is also what handles my email addresses. I am not fond with the fact there are no catch-all options anymore, but I made due with that, and adjusted. However, if I was to find a host? that would offer a catch-all, I will move one of my domains to there, and use the email catch-all while keeping my current email address with my current hosting company.
If I was to acquire my own hosting company, I will then use the hosting provider for all of my websites, and assure that I will have a service that I will be happy with since this is a realistic hosting service provision.
