TechnicalInfo.net is a collection of passive information gathering tools, many of which fail by redirecting to swisscom. Includes some of the Sam Spade tools, which can tell you what others can easily learn about you. The Sam Spade tools look up DNS and domain information.

Search Engine Optimization (SEO)
Expectations. It’s all about expectations. Getting a search engine to refer to your web site appropriately requires an understanding to what the search engine crawler does, what it expects to find, and how to address those expectations.

Web of Trust Unfortunately, no one checks to see what the community has reported in order to interpret the WoT score. They look no further than the raw score. The WoT raw score is largely useless; if it is low, then why? What is the complaint? Two “very poor” ratings can result in a poor reputation score. If it high, then why? Perhaps only one person bothered to rate it.

urlQuery.net is a (beta) service for detecting and analyzing web-based malware. It provides detailed information about the actions a browser takes while visiting a site and presents the information for further analysis. It uses Intrusion Detection Systems (IDSs) (Suricata with Emerging Threats and Snort with VRT), reports about the ASN, reviews the Java scripts, reports requests and responses.
hosts-file.net maintains net block lists and links to many web site information sources.
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.
