 <b>Dynamic Router Keys: </b>
 <input type="checkbox" class="optbox" name="dynamicKeys" value="true" <jsp:getProperty name="nethelper" property="dynamicKeysChecked" /> /><br>
 <p>
 This setting causes your router identity to be regenerated every time your IP address
 changes. If you have a dynamic IP this option can speed up your reintegration into
 the network (since people will have banned your old router identity), and, for
 very weak adversaries, help frustrate trivial
 <a href="http://www.i2p.net/how_threatmodel#intersection">intersection
 attacks</a> against the NetDB.  Your different router identities would only be
 'hidden' among other I2P users at your ISP, and further analysis would link
 the router identities further.</p>
 <p>Note that when I2P detects an IP address change, it will automatically
 initiate a restart in order to rekey and to disconnect from peers before they
 update their profiles - any long lasting client connections will be disconnected,
 though such would likely already be the case anyway, since the IP address changed.
