Do websites that share an I.P. address have a handicap when it comes to search engines???,
I have a resellers package, which allows me 30 sites, I just wanted to know if there is any draw back to the sites having the same ip address??.

One drawback might be that if you crosslink excessively search engines will see it as link spamming. Also, if a website on your IP is blacklisted (say it's being used to send spam) than your website won't be accessible to others. This is why many webmasters hate being hosted with pornography websites (they are known for spyware, etc. which can get them blacklisted).

Search engines look at the ip blocks where incoming links come from and not just individual ip addresses. So having 30 incoming links from xxx.xxx.xxx.xx1 is no better or worse then 1 link from xxx.xxx.xxx.xx1 and another from xxx.xxx.xxx.xx2, etc...

For that reason having 30 sites on 1 ip address will not harm you from a search engine stand point. This same reason also applies to how spam blacklisting is handled as well.

IP addresses are really only needed for two things.

1) anonymous ftp
2) have a ssl certificate

Very well stated...

I will add 1 item to your list of "when can you JUSTIFY and NEED a Dedicated IP"

3) setting up private nameservers (reseller hosting clients only)

Thanks for the comment.

I was going to add the #3 you stated, but figured with many hosts now allowing of sharing nameserver ip's that I wouldn't. But of course you are right, #3 is another reason requesting an ip addy.

I think a dedicated IP can also be used to host high risk site (prone to Ddos attacks).
That way, if an attack comes in (more than you can handle) and you remove the offending IP, then the attack can be stopped. Right??

Its however a different story that this is NOT the right way to mitigate a DDOS attack. But a very crude way.

Or you could just use mod_security to drop any packets going to the site being attacked.

I personally like dedicated IPs - that is one of the reason's for starting my own company - always getting charges extra for it.

the hosting clients that we have all have them - at one point or another you stumble accross something that would be of benefit when having a dedicated IP

here are the main uses / benefits

- Private SSL Certificate - SSL certificates are needed for accepting credit cards online. Most web hosting companies usually offer a shared SSL certificate where clients can share the web host’s server-wide SSL. This is not recommended if you intend on having a very secure online store.

- Anonymous FTP - Anonymous FTP is a method of sharing files on the Internet. Anonymous FTP means a server will allow anyone using an FTP software access to a public directory. This service is called Anonymous FTP because the user name used to sign in is "anonymous." To enable anonymous FTP many web hosting companies will require a dedicated IP for the anonymous FTP function to work properly.

- Private Domain Name Server - An example of a name server would look like this: [NS.REBELNETWORKS.COM, NS2.REBELNETWORKS.COM]. Since all web hosting companies provide you with their DNS servers, you don't need to have your own. But if you choose to have your own name server you will need to have a dedicated IP address to do so.
