Search Engine Optimization (SEO)

Of particular interest is vURL Online. Quickly and safely dissect malicious or suspect websites.
The following message from hpHOSTS (about the IP address not matching the PTR record) should not influence your decision to trust the website or ISP. Consult the IP reverse DNS feature of robtex.com or the Domain Dossier feature of CentralOps.net as a convenient mechanism to review DNS records. I find that the IP address often matches the PTR record, contrary to the message.
WARNING: The IP PTR associated with this record, does not resolve. This is considered very bad practice and contravines (sic) the RFC Standards. Most legit ISP’s will have their PTR’s resolve to an IP.
