Here's a list of all the subdomains and what they point to as well as their types:

(A) cometpingpong.com -> 54.77.45.224
(CNAME) autoconfig.cometpingpong.com -> moz-autoconfig.jimdo-platform.net
(CNAME) autodiscover.competpingpong.com -> autodiscover.emailsrvr.com
(CNAME) www.cometpingpong.com -> web.prod.aws.jimdo-server.com
(MX) cometpingpong.com -> mx1.jimdo.com (Priority: 10)
(MX) cometpingpong.com -> mx2.jimdo.com (Priority: 20)
(TXT) cometpingpong.com -> v=spf1 include:spf.mandrillapp.com include:sendgrid.net include:emailsrvr.com ~all
(TXT) google._domainkey -> [redacted]
(txt) mandrill._domainkey -> [redacted]
(TXT) smtpapi._domainkey -> [redacted]
(TXT) smtpapi._domainkey.em -> [redacted]
(TXT) smtpapi._domainkey.email -> [redacted]

They seem to use a mixture of Amazon Web Services (AWS) as well as other services: SendGrid (used to send bulk email such as newsletters and other things like advertisements) They seem to use a hosted email solution linked to (amazon?)

They seem to use a lot of txt-related records for verification (omitted because they can be used to spoof domains) to verify their domain for various services.

Their website is hosted on AWS (assume it is a EC2 instance) and is most likely managed by a entity other than comet themselves (due to lack of technical knowledge)

I have only included stuff that is available to public knowledge. They have literally no protection what so ever for their domain or their servers from what I can tell (assuming from the fact that I was able to pull all these records from their website).

Besta Pizza's website is also hosted on Amazon Web Services:

(A) mybestapizza.com -> 50.16.177.65
(CNAME) mail.mybestapizza.com -> email.secureserver.net
(CNAME) ftp.mybestapizza.com -> mybestapizza.com
(CNAME) www.mybestapizza.com -> mybestapizza.com
(MX) mybestapizza.com -> mailstore1.secureserver.net (Priority: 10)
(MX) mybestapizza.com -> smtp.secureserver.net (Priority: 0)
(NS) mybestapizza.com -> ns51.domaincontrol.com
(NS) mybestapizza.com -> ns52.domaincontrol.com

WHOIS for both domains: http://archive.is/xxKWn - besta pizza http://archive.is/9N9jF - comet ping pong

This information is public domain so I didn't have t use any exploitative methods to get this information. This information can be gotten if you know how to get them (which they are public domain)

I do not have access to any of this information (other than using public knowledge) in any way that would be considered illegal. This information is extremely easy to get and isn't hard at all if you know how DNS works.
