Namealong takes your query, pairs it up with 4000+ other words, suffixes, and prefixes, and shows you available .com domains by checking the ICANN zone file.<p>That's fast, but semi-inaccurate, so when you hover over or click on domain names, an additional WHOIS check is done to verify availability.<p>If this all sounds familiar, Lean Domain Search used to do this exact same thing, but earlier this year they added .blog domains to the search results with no way to filter them out, making the tool basically useless for .com searches.
