Hi Peter,<br>
<br>
a fix has been pushed for that. <br>
<br>
Interesting - and nice - to see people trying to run v6 only :-)<br>

up on André Grüneberg's thread from August 19/2023 titled "No IRRDB
shown for IPv6 only peer" (<a target="_blank" href="https://www.inex.ie/pipermail/ixpmanager/2023-August/003709.html" moz-do-not-send="true">https://www.inex.ie/pipermail/ixpmanager/2023-August/003709.html</a>),
I noticed that the same situation is occurring for us in our IXPmanager
instance. This unfortunately prevents us from filtering an IPv6-only
member on our route servers, meaning that we have to allocate and
"waste" an IPv4 address for that member.<br></div><div><br></div><div>I
