Every domain that contributes links to your target page is listed in the table here. The default sort order is by "Link Count," which is the total number of links from the domain to our target page. To easily find a domain name in a more lengthy table, click the "Domain Name" column lable to sort by domain name.
The Link Count is the total number of links found from pages at the listed
domain that link to our target page. For example, if a domain has two pages
that both link to our target page, one of them with a single link and the
other with two links, we will see "3" as the Link Count for the domain.
To find links that are close together in terms of IP address, sort by the third column. This may be an important exercise for "mini-webs" of related sites as there is some evidence that search engines are de-weighting links from the same Class-C IP address.
The Class C portion of the address is the first three numbers, for example 216.74.123.99 is in the same Class C block as 216.74.123.62 since the first three groups of numbers match. Using the same example, the IP 216.74.102.62 is in a different Class C block.
