<p class="MsoNormal">Dear colleagues of the Address Policy Working Group,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">During (my first!) RIPE85 there was short discussion about the minimal size for IPv4 temporary assignments in this workgroup.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The policy for temporary IPv4 assignments requires you to use 50% of the assigned addresses [1].<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This requirement pushes events or experiments into smaller assignments less than /24’s, which are mostly unroutable on the internet.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This is mentioned before by Marco Schmidt [2] in October 2022 and Randy Bush [3] in Januari 2022.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It looks to me this is a legitimate reason to propose this in a policy change:<o:p></o:p></span></p>

and advertise by themselves).<o:p></o:p></span></li></ul>
