This allows to leverage the server to search for <strong>ASNs</strong>, <strong>URLs</strong>, <strong>IPs</strong>, <strong>Hostnames</strong>, and so on, depending on the search string.</p> <p dir="auto">Generally speaking, this implies instructing the browser that when a certain <strong>keyword</strong> is prepended to a search, the following characters (the actual <strong>search string</strong>, identified by <code>%s</code>) have to be passed to a certain URL. The URL is then composed according to this logic, and opened just like a normal webpage.</p> <p dir="auto">I've used <code>@asn</code> for my keyword, but anything would do. In order to speed up things, one could very well use a shorter tag (e.g. <code>#</code>) that, when used in the address bar, automatically switches your search engine to the ASN Lookup server. Note that the leading <code>@</code> sign is not mandatory, just handy since it doesn't get in the way of normal searches, but there's much freedom with that.</p> <p dir="auto">For quick reference, the location URL string to enter (for both Firefox and Chrome) is: <code>http://127.0.0.1:49200/asn_lookup&%s</code>.
