Or we could just complain to the operators of the servers that echo EDNS options and request that they fix them. It's not like it isn't a fixable problem. It just requires a little co-operation to find and report broken servers to the operators and willingness to follow through when servers are not fixed. Below is list of servers that echo unknown EDNS options and don't also return BADVERS / FORMERR from yesterdays EDNS compliance run. a.ns.mtgsy.com, acerinternet.acer.edu.au, audns02.ibisworld.com.au, aunddwgdns01.didata.com.au, azdpsdns.dps.state.az.us, azdpsdnsii.dps.state.az.us, bloodaxe.iad.gov, bloodgem.iad.gov, cns1.courts.state.tx.us, cns1.txcourts.gov, cns2.courts.state.tx.us, cns2.txcourts.gov, copns3.phoenix.gov, copns4.phoenix.gov, diamond.msha.gov, disa.tenet.ac.za, dns0.mtgsy.com, dns01.henley.com.au, dns03.australiasoutheast.cloudapp.azure.com, dns1.chisholm.edu.au, dns1.edmonds.wa.us, dns1.hcshostit.com, dns1.manchesterct.gov, dns1.markum.net, dns1.netsource-one.net, dns1.springfieldcityhall.com, dns1.uk.hub.oup.com, dns1.webstarthost.net.au, dns2.chisholm.edu.au, dns2.hcshostit.com, dns2.jpc.qld.edu.au, dns2.manchesterct.gov, dns2.markum.net, dns2.name-s.net, dns2.netsource-one.net, dns2.springfieldcityhall.com, dns2.webstarthost.net.au, dns3.edmondswa.gov, dns3.jpc.qld.edu.au, dns3.manchesterct.gov, dns3.mtgsy.com, dns4.manchesterct.gov, dns4.mtgsy.com, dns4.perpetual.com.au, doldns02.dol.com.tr, js2.objware.com.au, lv3ns1.ffdns.net, lv3ns2.ffdns.net, lv3ns3.ffdns.net, lv3ns4.ffdns.net, lv4ns1.ffdns.net, lv4ns2.ffdns.net, lv4ns3.ffdns.net, lv4ns4.ffdns.net, name2.deloitte.com.au, name3.deloitte.com.au, ns-au1.xhostsolutions.net.au, ns-au2.xhostsolutions.net.au, ns.acmi.net.au, ns.didata.com.au, ns.hotelsaccommodation.com.au, ns.liturgyhelp.com.au, ns.media3.net, ns.ouronlinecanteen.com.au, ns.studio-moderna.com, ns.trustdeed.com.au, ns.tut.gov.tr, ns0.demysdns.net, ns0.stirling.wa.gov.au, ns0.technique-ltd.co.uk, ns01.trademarkarea.com, ns1-03.azure-dns.com, ns1-04.azure-dns.com, ns1.acnusa.net, ns1.aftrs.edu.au, ns1.agfgnetwork.com, ns1.ahg.com.au, ns1.aic.gov.au, ns1.andrewsairportpark.com.au, ns1.apra.gov.au, ns1.arlingtontx.gov, ns1.bloggersllc.com, ns1.bupaagedcare.com.au, ns1.careerhub.com.au, ns1.cityofnewportbeach.net, ns1.controlmyvps.com.au, ns1.cookeville-tn.org, ns1.demysdns.net, ns1.dnsserver5.net, ns1.erie.gov, ns1.garlandtexas.net, ns1.infoplum.com, ns1.maximumasp.com, ns1.msedge.net, ns1.mtco.com.au, ns1.nashville.gov, ns1.newportbeachca.gov, ns1.polkcountyiowa.gov, ns1.princegeorgescountymd.gov, ns1.rtomanager.com.au, ns1.sberbank.ru, ns1.state.nv.us, ns1.stirling.wa.gov.au, ns1.tupperware.net, ns1.vpsblocks.com.au, ns104.mschosting.com, ns1au.telethonkids.org.au, ns2-03.azure-dns.net, ns2-04.azure-dns.net, ns2.acnusa.net, ns2.ahg.com.au, ns2.alacourt.gov, ns2.andrewsairportpark.com.au, ns2.apra.gov.au, ns2.arlingtontx.gov, ns2.aspcomputers.com.au, ns2.auzgc.com, ns2.bloggersllc.com, ns2.careerhub.com.au, ns2.cityofnewportbeach.net, ns2.demysdns.net, ns2.didata.com.au, ns2.dnsserver5.net, ns2.erie.gov, ns2.ispnet.com.au, ns2.mainroads.wa.gov.au, ns2.maximumasp.com, ns2.media3.net, ns2.msedge.net, ns2.mtco.com.au, ns2.objware.com.au, ns2.princegeorgescountymd.gov, ns2.sberbank.ru, ns2.state.nv.us, ns2.studio-moderna.com, ns2.tupperware.net, ns3-03.azure-dns.org, ns3-04.azure-dns.org, ns3-au.computershare.com, ns3.alacourt.gov, ns3.bccdns.com, ns3.demysdns.net, ns3.elmtree.net.au, ns3.msedge.net, ns3.rtomanager.com.au, ns3.scstatehouse.gov, ns3.tlr.net.au, ns3.torqueit.com.au, ns3.tupperware.net, ns4-03.azure-dns.info, ns4-04.azure-dns.info, ns4-au.computershare.com, ns4.demysdns.co.uk, ns4.msedge.net, ns4.scstatehouse.gov, ns4.tlr.net.au, ns5.demysdns.co.uk, ns5.elmtree.net.au, ns6.bluesoap.com.au, ns6.demysdns.co.uk, offsite1.cmsit.com.au, otw-dns-1.gbst.com, otw-dns-2.gbst.com, pbnedns2001.suncorpmetway.com.au, pbnedns2002.suncorpmetway.com.au, pdcpns01.lionco.com, primary-dns.edmonds.wa.us, samappdn.samsung.com.sg, samappdnc.samsung.com.sg, samapsdn.samsung.com.sg, samapsdnc.samsung.com.sg, sdcpns01.lionco.com, sdns1.miamidade.gov, sdns2.miamidade.gov, sdns3.miamidade.gov, secdns.sharp.net.au, server01.cub.com.au, spdns2.pima.gov, spdns3.pima.gov, storagemanager.controlmyvps.com.au, utc.utcourts.gov, vdns1.asi.com.au, vdns2.asi.com.au, vdns3.asi.com.au, vmh18607.hosting24.com.au > Ray -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: [email protected] _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
