What does "pre-screened" mean? It means we check the ranges to see if they are clean prior to deployments. AOL Hotmail Yahoo SBC, etc.. Different hosting clients are looking for different things. Some are specific to TLD's while others are looking for SEO or GEO/IP's. These are not VIRGIN ranges, although we have some of those also. These are simply "pre-screened" so there is no 'luck of the draw'. Additionally, we only offer this service on /24 (Full Class C) or higher. Feel free to contact me directly via PM with any questions or your specific needs. With /24's an above, we prefer 3 month minimum commitment terms. When in contact, please be clear as to you needs and uses.
