Web hosting/domain registrations etc
So I've got a couple of domain's registered (.co.uk's) and I've arranged some basic hosting for one of them.
I've opted not to have my detail's on the Whois register, but I know that the domain's have got the company that I registered them through as the admin/technical contact.
I understand that it's better if I have thing's so that I'm down as the admin/technical contact myself, but I don't quite follow why, so can someone explain the "pro's and con's" of this?
Also, maybe someone could explain if I need to arrange/have any other facilities i.e. do I need to run my own webservers etc to do this? Would I need to have a static IP address? or is it normal that I can be down for all the detail's and still use "third party" hosting facilities?
I've tried googling for info, but as you'd expect, all I get are hit's for various companies that are offering to host stuff for me.
p.s. sorry if this sound's like rather dim questions, but I'm only just getting into this sort of stuff and suffering from mega info overload - working out the salient point's isn't as straight forward as it seem's!
