<div>Hi,</div>
<div><br>
</div>
<div>What you could consider is asking a few of the major internet exchanges if they'd be so kind to send you a list of MAC addresses seen on their LANs. Based on the MAC you can determine the manufacturer. If you have three or four big ones, you have a decent
sample size as most larger networks are on multiple IXes anyway.</div>
<div><br>
</div>
<div>If you do compile a list, I'm sure this list would be interested in the results :)</div>
<div><br>
</div>
<div>Thanks, <br>
<br>
Sabri <br>

<p class="x_MsoNormal">Hi, I am working with MANRS (<a href="https://www.manrs.org" target="_blank">https://www.manrs.org</a>) on a tool for checking router configs for BGP security / spoofing prevention (e.g. uRPF)
<a href="https://github.com/manrs-tools/MANRS-validator" target="_blank">https://github.com/manrs-tools/MANRS-validator</a></p>
<p class="x_MsoNormal">We are wondering if there is any research on the percentages of different types of devices running BGP on the Internet.
</p>
<p class="x_MsoNormal">Something like:</p>
<p class="x_MsoNormal">Cisco IOS 30%</p>
<p class="x_MsoNormal">Junos 30%</p>
<p class="x_MsoNormal">Mikrotik 20%</p>
<p class="x_MsoNormal">etc…</p>
<p class="x_MsoNormal">We are looking to focus our tool on the most prevalent types of devices doing BGP (and the most prevalent with BGP security/spoofing issues) so that we can have the greatest impact. Does anyone have any information on this or know where
I can obtain this information? Thanks in advance!</p>
