Good God!

Hmmm, of course, the reason they need that many MX's is that they
appear to be up to no good. The SenderBase folks give them a "Poor"
web reputation (suspected malware and phishing attacks). And they
appear to own the entire 208.100.37-38 IP range (no wonder IPv4 is
running out of addresses!). Gotta love their company name, too. The
whois on (for example) 208.100.37.131 lists "FragnServers.com".

So... I'm not entirely against the idea that an email system should
never be able to send email to those guys. ;D

But that was worth the OMG factor. Thanks for sharing!

This just blows my mind:

$ dnsq any mountaingeardirect.com ns0.mountaingeardirect.com
255 mountaingeardirect.com:
9706 bytes, 1+258+0+255 records, response, authoritative, noerror
query: 255 mountaingeardirect.com

Astounding! Simply Astounding!

Thanks for sharing,

Andy
