Ever wondered how many or what sites are hosted on the same ip address that your site is hosted. Domainbyip makes it really easy to find these sites. If you know you ip address for your shared host enter it on DomainByIP and it will list all the sites that are hosted on the same IP. If you dont know your ip address, domain by ip has the answer for that too. DNS name look up will find the ip for your site. I think this tool might come in handy.
You might ask what this has to do with Search Engine Optimization. Even though search engines dont mind multiple sites hosted on the same IP address, your ranking might be affected if there is a spam site hosted on your shared IP.
To avoid this problem I recomend hosting your site on a dedicated virtual server wiht a dedicated ip, since they are very affordabe now.
