<div class="">Dear All, </div>
<div class=""><br class="">
</div>
<div class="">Since 2019 06 05 around 10:00 UTC I see a much higher number of queries to our name servers for top level dot (.) </div>
<div class="">This happened before too from anywhere but with an amount of queries of 5 to 10 times per day. Now we are in a range of average 2000 queries per hour up to 7200 queries per hour. </div>
<div class=""><br class="">
</div>
<div class=""><img apple-inline="yes" id="4D65013A-AF91-4F23-AD0B-E467F28F070C" src="cid:FBEFFA9F-3523-463B-9463-33A11B633B52" class=""></div>
<div class=""><br class="">
</div>
<div class="">Interesting is that only one of our 4 DNS server is used for these queries. </div>
<div class=""><br class="">
</div>
<div class="">All these remote IP’s are coming from WEBEX. A reverse lookup ends with
<a href="http://something.webex.com" class="">something.webex.com</a> </div>
<div class="">The geo-locations are limited to 4 destinations </div>
<div class="">US, <span style="color: rgb(45, 45, 45); orphans: 2; white-space: pre-wrap; widows: 2; background-color: rgb(255, 255, 255);" class="">San Jose</span> </div>
<div class="">Netherlands</div>
<div class="">Repulic of Singapore, Singapore </div>
<div class="">China, <span style="color: rgb(45, 45, 45); orphans: 2; white-space: pre-wrap; widows: 2; background-color: rgb(255, 255, 255);" class="">Beijing</span></div>
<div class=""><br class="">
</div>
<div class="">Did anyone else register this obviously misconfigured DNS from Webex ? </div>
