<p>Hi,</p>
<p>Running a webserver on a home system suffers from the problem of
IP Address changes after modem reboot.</p>
<p>In Australia with the National Broadband Network (NBN) I am also
experiencing IP Address changes without the modem disconnecting.
It may not be general, but in my case it seems that a fixed IP
Address is not available. <br>
</p>
<p>Also, when server is on a laptop it would be nice to be able to
have the server available at different locations. <br>
</p>
<p>Using dynamic DNS it takes some time for the new address to work
through the system, due to isp dns caching etc.</p>
<p>Having a domain name and LetsEncrypt certificate for the home
server what methods are available to handle IP address changes
fast.</p>
<p>In researching the subject one solution might be to use a SAN
certificate with 2 domain names. The first domain being a site to
redirect to the home server using the second domain name. But the
redirect would have to be to an IP address, not domain name!<br>
</p>
<p>Another possibility is to use "DH_anon" cipher suite but I have
no real idea how this works. This would probably be the best
solution as I have a secure back channel network that can be used
to update the ip addresses and for any authentication and
authorization purposes.<br>
</p>
<p>Any suggestion how to handle this?</p>
