kasperd<p>Thanks to IPv6 I can route an IP prefix to my laptop and use it for developing software in Docker containers. The software can use this to connect to a database hosted at a cloud provider which is shared with other developers.</p><p>Since there is no NAT I don't have to worry about TCP connections stalling when the NAT times out connections.</p><p><a class="hashtag" href="https://westergaard.social/tag/howipv6helpedmethisweek" rel="nofollow noopener" target="_blank">#HowIPv6HelpedMeThisWeek</a></p><p>For security the database is protected using both an IP whitelist and TLS certificates for both client and server.</p>

kasperd<p>A website I manage has been subject to some port scans and subsequently a management interface on a separate port number has seen password brute force attempts.</p><p>Since IPv6 gives me enough addresses I have moved the management interface to a different IP address.</p><p>IPv6 has so many addresses that scanning all of IPv6 address space is not feasible. So scans use other methods such as scanning known domain names.</p><p>If you have multiple domain names pointing to your host they don't all have to point to the same IP address.</p><p><a class="hashtag" href="https://westergaard.social/tag/howipv6helpedmethisweek" rel="nofollow noopener" target="_blank">#HowIPv6HelpedMeThisWeek</a></p>
kasperd<p>I am considering the idea of writing a weekly post <a class="hashtag" href="https://westergaard.social/tag/howipv6helpedmethisweek" rel="nofollow noopener" target="_blank">#HowIPv6HelpedMeThisWeek</a> giving one example of something useful IPv6 has done for me in the past week.</p><p>I am aware that it may be challenging to come up with a novel example each week. And really it does not necessarily have to be novel in order to count. Doing the same useful thing each week is still useful. But the posts will obviously be more interesting, if I don't repeat the same thing week after week.</p><p>It may also be challenging to notice each time IPv6 does something useful because we tend to notice things which are broken rather than things which are working. And IPv6 just working is the experience I have most of the time when connected to networks with native IPv6.</p><p>It would probably have been easier to come up with a weekly post about how IPv4 annoyed me in the past week. But if I want to make this a regular thing, I should focus on the positive things and not turn this into IPv4 bashing.</p><p>The hashtag is of course not only for me to use. I am not the only person who have had positive experiences with IPv6.</p>
