I've just started with a dedicated server and am migrating 5 sites to it.

With the hosting plan, you purchase IP addresses as needed (none were included initially).

You have to purchase at least 1 IP (for your first website). In the control panel they list that website as having a "dedicated" IP.

For your remaining websites, they can all be "shared" hosted on the same first IP. (So it really seems as though all of the sites are shared IP hosted.)

4 of my websites are of minor importance to me, they will all share the same IP.

One of my sites is very important to me and it is the last one I will bring to this server.

My question is, should I purchase a second IP address for this single website? Is there an advantage to doing so?

1) The cost for the IP is very minimal, and not necessarily an issue. But why spend money for no reason.
2) I full understand inter-site linking and the value of separate IP addresses. That's not concern in my situation.

In regards to handling traffic, server load, ranking, really anything at all, would purchasing a dedicated IP for this one (most important) website provide any service or benefit?

The only ranking concern I know of is that if some other sites on the same IP address are bad neighborhoods, are used in linking schemes or use other shady techniques, it may affect rankings on other sites on that IP address. Technical problems with multiple sites on one IP are only present if you use SSL certificates. Traffic, site response and other aspects of your appearance on the web are not influenced by using one or multiple IP addresses.

FYI, www.webmasterworld.com and www.pubcon.com are both on the same IP address. If Brett would have had the slightest feeling that separate IP addresses would benefit either of the two sites, he would probably have split them over separate addresses.

If you wnat to have your own DNS service you will need two IP's more.
Most control panels offers easy DNS setup but if you're always programming and testing, resetting and so on, you'll better use the company's DNS.
