The discussion in the Open-IX community seems to support a CI change<br>
related to IXPs in the following manners:<br>
<br>
- use sparse allocations for CI space<br>
<br>
Helps to avoid renumbering of growing CI. We will use the suggestions<br>
process for this.<br></blockquote><div><br></div><div>Seems entirely reasonable and uncontroversial to me.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
- increase the reserve pool to a /15<br>
<br>
Appears to be rather rapid depletion of CI pool based on the recent<br>
acceleration of NA IXP growth related to multiple party efforts<br></blockquote><div><br></div><div>If we as a community think that IXP allocations are valuable enough to the larger community to justify reserving space that would otherwise go to operate networks, I don't have any particular objection to this.

- increase the minimum allocation for an IXP to a /22<br>
<br>
IXPs are deploying much larger footprints from day 1 vs. growing into<br>
multiple facilities. More avoidance of renumbering of CI.<br></blockquote><div><br></div><div>I don't see the justification for this change. Granting a /22 to all IXPs, even if their growth plans don't indicate they're likely to need it, seems excessive, particularly in light of sparse allocation, where the IXP can simply grow into a large subnet by getting new participants (and those they peer with) to change their subnet mask, without any renumbering efforts or flag days.</div><div><br></div><div>IMO it'd be better to let small IXPs start with a /24 (or even smaller), so that in the eventual future when the reserved IXP CI block is full, we can sparse-allocate other small IXPs a /24 out of the original reserved /22 if the original IXP still hasn't expanded.</div><div><br></div><div>-Scott</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

On the renumbering issue, I do agree that this is different<br>
considering that we have placed them in the class of CI along with the<br>
others.<br>
<br>
By no means have I offered exhaustive justifications for any of the<br>
above points. Rather, points to test the waters.<br>
<br>
YMMV,<br>
