    Is there a way to do this before you buy? Find out what IP address ranges a hosting provider controls?

    I need to do some emailing. But I have to make sure that my prospective host isn't already on any of the prominent RBLs before I pay.

    do a whois on any ip they have and it will usually provide a scope, although they may have many more scopes than the one you drill into

    Thanks for the reply. Now that I've answered my own question, I'll provide what I discovered so that others might benefit from my search.

    Unravelled is right - you need to do a whois. But not just a whois at any old place. Most whois will tell all the domains hosted at a given IP address - but only for that 1 individual IP address.

    If you do the save whois at ARIN - it will tell you the entire "net range" of IP blocks controlled by the entity to which the IP in question is assigned.

    So, when you're thinking about using a given company's hosting services, do a whois on the domain name to find out the the IP where the hosting co's main website is hosted. Then take that IP and go to arin to find out the "real" entity behind the hosting company and what IP addys it controls.

    Make sure none of those addresses are on RBLs if you're going to any emailing whatsoever.

    Yea, you should get your own static IP for your shared hosting account.. that way your not on a shared IP. So if someone on your shared server spams your IP won't be black listed..

    Unless I'm mistaken (possible) what you are saying is fundamentally, by definition, impossible.

    A shared hosting account is an account where you share an IP address with many (usually 100s) of other domains.

    you can be on a shared host with a shared IP, but you can request a dedicated IP for your shared hosting, if say you need ssl to secure your admin section and sign ups..

    Shared hosting basically means that on one server you share your space with other clients.. your site is not the only one hosted on that server, there is multiple sites from multiple clients and they all share resources like cpu and disk space..

    Hope that helps..

    I forgot to mention that there would be an additional charge for getting a dedicated IP, typically it's an extra $1-$2/month..
    an ssl certificate would also be an addtional charge.. normally you can get these from say godaddy..

    That's a good question.. maybe it depends on the PR of the site..

    You're probably right - but I had no idea that one unique physical machine (such as a server) could have multiple IP addresses. I thought each host (device) on a network needed to have a unique IP address. I guess not. I guess I have a fundamental misunderstanding of how networking works and I need to read a book about it.

    It is my understanding that your site cannot be punished for who links to it. However, your site can be punished if you link to a junk site.

    Think about it - if it were as simple as linking to a "good" site with junk sites in order to drag the good site down, then everyone would just make autogen spam blogs linking like hell to their competitors; who in turn would do the same.

    It'd be a perpertual "shit flinging" contest to see who could drag the other down the most the fastest. So I highly doubt you have to worry about it.

    Well I don't think the actually server can have more than one IP per network card..

    Also it's harder to get an IP now.. since supposedly there is a shortage of it..you have to justify what you need the ip for..

    There is already a new format called IPv6.. but it's not widely used in north america
