# Implementation Details
-## About Lookups
+## How does KadNode works
+
+This is the progress for a domain lookup in the browser using TLS and a PKI.
+
+1. A domain like example.com.p2p is entered in the web browser.
+2. The request is filtered by KadNode on the system level via a local DNS proxy or NSS support.
+3. The domain is hashed and a hash lookup on the DHT network is performed.
+4. Zero to multiple IP Addresses are returned by the DHT.
+5. To every IP address, a TLS session is established. If it succedes, the IP is verified.
+6. The verified IP addresses are based back from KadNode to the browser who establishes a HTTPS session to access a website.
+
+## About Annoucement
An announcement is done every 20 minutes. The lifetime of those entries on other peer is expected to be around 15 minutes.
Search results will be cached for about 20 minutes. If a lookup is done after 10 minutes after the search has been started, the search will be restarted and the cached results will be returned.
