Bernstein" To: namedroppers@ops.ietf.org, drums@cs.utk.edu Subject: 10000 *.com dotted-decimal MX records Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii This isn't news to MTA implementors; most MTAs---and the vast majority by volume---deliver to these domains without trouble. But apparently it's news to some DNSEXT and DRUMS participants, notably Randy Bush, who has been discarding messages to the DNSEXT mailing list on this topic. Shown below are 58 examples of .com domains whose MX records include dotted-decimal IP addresses for currently reachable hosts. In most cases there is only one MX record. Several of the MX records point to a single address, but overall there are many different networks. These examples are all from a verifiable 1/256th sample of .com domains: namely, those with MD5 checksums starting with eight zero bits. Try ``echo -n FASB | md5'', for example. Evidently there are roughly 15000 *.com domains whose MX records include reachable dotted-decimal IP addresses. Roughly 10000 of them have no other MX records. ---Dan AAPAINTING.com: 216.149.170.212 ANOKAEQUINE.com: swconsulting.com 207.1.200.130 ASSESSINGCO.com: 208.232.239.130 ohare.sharpsite.com oboe.sharpsite.com BENTZEL-INSURANCE.com: 24.104.49.250 polaris.blazenet.net sirius.blazenet.net BOBYOAKFORD.com: 38.201.236.1 pop.ruralnet.org BODYCONTACT.com: bodycontact.com 207.106.19.173 astraweb.com CAMERABUSINESS.com: 209.240.132.38 CARDIOBEAT.com: 204.245.52.113 CAROLINACATFIGHTS.com: 207.173.185.5 CKINC.com: 216.112.96.18 COLORADOMOTORS.com: 216.120.21.219 COUVRETTE.com: 209.245.55.70 DANHOLM.com: 193.75.78.148 DANTHEMORTGAGEMAN.com: 209.69.26.5 DREAMBIZ4ALL.com: mail.daretolive.com 199.120.110.200 DRUGDIGEST.com: 208.134.198.19 DSPFILM.com: mail.thejunkie.com 64.24.9.173 ENRON-COMMUNICATIONS.com: 209.51.83.242 ns.networkmercenaries.com EZALLOTMENT.com: 63.64.5.189 FASB.com: 205.138.121.66 FIREPLACE-SPA.com: 209.142.210.105 FRENACK.com: 209.240.132.38 GUILDPAGES.com: 63.193.74.202 HEARTOFFLORIDA.com: 205.161.237.18 HUNKS2WATCH.com: 207.155.50.213 INETFILM.com: mail.thejunkie.com 64.24.9.173 JAWSANDCHUCKS.com: 209.203.204.38 mail.huronmachine.com KELLYALEXA.com: 209.240.132.38 KIDBEEPER.com: 209.240.132.38 KITCHENARTOFSOUTHFLORIDA.com: 209.240.132.38 LATINBOOTY.com: 209.51.241.24 mail.dreamcom.net LEATHERVESTS.com: 209.240.132.38 MALL4NET.com: 205.252.89.125 MCINTOSHCOLLEGE.com: 209.6.156.190 MINDLIFTER.com: 195.94.56.80 PEMPEO.com: 209.186.123.131 PERSONALCAPTIONING.com: 63.64.5.189 PILOTSINTOUCH.com: 209.240.132.38 PROFILESNORTHTEXAS.com: 208.232.239.130 ohare.sharpsite.com oboe.sharpsite.com PROFILESWISCONSIN.com: 208.232.239.130 ohare.sharpsite.com oboe.sharpsite.com QUEENOFHEAVEN.com: 209.240.132.38 RAPIDEC.com: 209.240.132.38 REVOLUTIONIZE-U.com: mail.daretolive.com 199.120.110.200 SACRAMENTOJOBS.com: 209.246.147.34 SAFEMATCH.com: 209.218.111.61 SANDIEGOCOUPONS.com: 204.216.147.42 SHARPMECHANICS.com: 199.2.50.28 SINSURFER.com: 209.240.132.38 SPRINGCREEKPRAMS.com: 207.149.11.4 mail.web-o.net STORE4989.com: 209.240.132.38 TECHNE-VI.com: 195.31.245.216 mail-backup.meditnet.com THESINCLAIRCOMPANY.com: 208.179.77.7 mail.thesinclaircompany.com mail.pajo.com THEWIRENUT.com: 207.254.129.96 TOLLGAS.com: 209.181.244.4 TRIPLECCC.com: xmail1.prime-c.com 216.201.147.38 UNITEDLEGWEAR.com: 208.248.127.42 earth.cosmoweb.net moon.cosmoweb.net VADHYAR.com: 209.240.132.38 WAP-BLITZER.com: 209.240.132.38
