So the recommendation to get that /24 is to cheat or otherwise mislead in your justification? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "William Herrin" <bill () herrin us> To: "Justin Wilson" <lists () mtin net> Cc: nanog () nanog org Sent: Tuesday, March 13, 2018 1:40:48 PM Subject: Re: IPv4 smaller than /24 leasing?

Even to buy it on the secondary market you have to have justification and show usage. So if someone buys a /24 and really only needs a /25 then what?
Hi Justin, If you can't justify a /24 with a single hypervisor, you aren't being creative enough. Seriously. Optimize your network _plan_ for address consumption. You need a /29 (or two /30s) to connect each VM to the primary and backup router VMs and that's before you assign virtual IPs to web servers on the VMs. In your initial allocation, ARIN won't hold you to your plan. You just have to have a plan where the numbers add up to justified need. If you're not comfortable going it on your own, contract someone who's been through it before to shepherd you through the process. ARIN's process is convoluted and arcane, but if you're ready to pay the cost of multihoming you truly won't have any trouble justifying an ARIN /24.
