WHOIS & HOSTING HISTORY LOOKUP — See extensive historical information including WHOIS, IP Address (website hosting), Name Server, Registrar and Screenshot history to help provide a complete view of a domain name's life cycle. When buying a domain from someone you may not know or trust, make sure you protect yourself by researching the domain's history.
SPF RECORD LOOKUP -- Sender Policy Framework (SPF) records allow domain owners to publish a list of IP addresses or subnets that are authorized to send email on their behalf. The goal is to reduce the amount of spam and fraud by making it much harder for malicious senders to disguise their identity. To learn more, visit the SPF Website @ http://spf.pobox.com/
