Contact your web host and tell them you would like your own unique IP address. To avoid any of the potential problems related with IP address sharing, it is best to acquire a unique IP address for your web site. Most providers receiving such orders reportedly use router-level filtering to disable access to the affected IP addresses, even though those IP addresses host scores of additional web sites without child pornography. For example, under 2002 law, the Attorney General of Pennsylvania ordered Internet service providers in Pennsylvania to disable access to sites found to offer child pornography. Sometimes Internet services providers are legally required to implement IP address level filtering. Additionally, research has indicated that IP address filtering is used by many commercial web filters installed in libraries and schools in the United States. Overblocking is a problem known to affect filtering in China, Vietnam, Saudi Arabia, and other countries that employ government-mandated country-wide web filtering policies.
Unfortunately, research has indicated that it is not atypical for a single web server to host a mixture of sites that are sexually explicit and sites that are not. If this happens, all other sites hosted on that IP address, regardless of their content, will be blocked as well. Overblocking occurs when a single website containing some form of adult or explicit content is blocked by its IP address. With so many sites sharing IP addresses, IP-based filtering efforts are bound to produce "overblocking", which is the accidental denial of access to web sites that abide by the stated filtering rules. "If you are an average webmaster and just running a few sites, I wouldn't worry about them being on the same IP address and I definitely wouldn't worry about them being on the same server. Matt Cutts, the head of Google's Webspam team, stated:
They would go through all of this trouble with one goal in mind - to game the search engines in order to bring in more organic traffic.įor most web sites, having a dedicated unique IP address will have little to no effect on search engine rankings. They would erase all traces that their sites are operated by the same individual. They would not use the same template on more than one web site. They would make sure that all of their domains were registered with different registrars under different names. They would host the web sites on completely different class C network addresses. An effective search engine optimizer would go further than hosting inter-linking web sites on different IP addresses.
Search engines devalue links from web sites pointing to other web sites hosted on the same IP address range.Ĭonversely, search engines value links from web sites hosted on different IP addresses. If the web sites are in the same IP address range, it is highly likely that they are operated by the same individual. One method that search engines use to detect this type of miscreant behavior is to see if these inter-linking web sites are hosted on the same IP address or IP address range. In an attempt to falsely inflate a web site's popularity, an individual may generate hundreds or even thousands of dummy web sites containing little to no content except for links pointing towards a specific domain name. While IP sharing is typically transparent to ordinary users, it may cause complications for both search engine optimization and web site filtering.Ĭoncerning SEO (search engine optimization)Īlmost all popular search engines (Google, Yahoo, etc.) increase a web site's rank based on the number of links pointing towards the web site. Simply put, most web sites are hosted on servers that host many other web sites. More than two thirds of these domains share their server with fifty or more additional domains. their web servers) with one or more additional domains. Since HTTP version 1.1, many domains can be hosted on a single IP address.Īs of 2003, more than 87% of all active domains names were found to share their IP addresses (i.e. Web sites are usually associated with domain names, textual strings like "" that are easier for users to remember than numeric IP addresses. Each web server typically has a single IP address, a unique numeric identifier assigned to no other computer on the entire Internet.

All web sites are hosted on web servers, which are computers running specialized software that distribute web content as requested.
