Enter up to 40 Domains (Each Domain must be on separate line)
Did you know that it is considered better to host multiple cross-linked sites on different Class C IP ranges? This nifty tool checks whether the same Class C IP range is hosting two or more domains, which will help you discover duplicate IP addresses and Class C blocks. Simply enter a minimum of two and up to 20 domain names (one domain per line) in the large text box and begin your test.
When you share an IP address with other sites, it can have a negative impact on the Page Rank and SEO efforts for your own website. When you share an IP address with other websites that have been blacklisted or intentionally blocked by search engines due to inappropriate content, it will have a negative impact on your website as well.
