Dedicated Hosting

I've been blogging for 3 years now and the only thing that confuses me still is the hosting and domain stuff. Three of my blogs are already in their own domain name however, the process in the beginning was quite difficult. I remember i went through setting up the dns and all that, good thing about it the customer service of the dedicated hosting i was using was fair enough to give me the knowledge to get through it. Having your own domain name is great. Everybody who venture the online businesses should consider this.
