From http://root-trust-anchor-reports.research.icann.org/ :

The ICANN org is publishing the IP addresses that are sending RFC 8145 telemetry ostensibly indicating that a resolver at the reported address (or another resolver that is forwarding through the resolver at the address) is validating using only KSK-2010 as a trust anchor. Publishing these addresses allows ISPs and other organizations who know who operates resolvers at those addresses to contact the resolver operator and notify them of the need to update their DNSSEC trust anchors. Without further action, these resolvers will stop working after the root KSK is rolled on 11 October 2018. http://root-trust-anchor-reports.research.icann.org/rfc8145-addresses.txt The following ASes have their country recorded as NZ in whois, and are in the ICANN list. The following resolvers may or may not be operated by the ASN identified. 4771 Spark 122.56.234.219 122-56-234-219.mobile.spark.co.nz. 122.57.192.56 122-57-192-56-adsl.sparkbb.co.nz. 122.61.118.222 122-61-118-222-adsl.sparkbb.co.nz. 219.88.186.152 rns6.xtra.co.nz. 222.153.3.78 222-153-3-78-fibre.sparkbb.co.nz. 222.154.149.63 222-154-149-63-fibre.sparkbb.co.nz. 9500 Vodafone 203.96.208.52 akrdns2.akl.vf.net.nz. 203.96.208.61 akrdns3.akl.vf.net.nz. 203.96.208.62 akrdns4.akl.vf.net.nz. 203.96.208.91 cbrdns1.chc.vf.net.nz. 203.96.208.92 cbrdns2.chc.vf.net.nz. 210.246.17.115 210-246-17-115.dsl.dyn.ihug.co.nz. 2407:7000:ff00:5382:bd9d::1 2407:7000:ff00:5382:bd9d::2 49.224.251.45 45.251.224.49.dyn.cust.vf.net.nz. 23655 SNAP 111.69.178.254 254.178.69.111.dynamic.snap.net.nz. 111.69.195.153 153.195.69.111.dynamic.snap.net.nz. 24183 DTS 202.174.180.228 38793 2degrees 118.148.149.52 52-149-148-118.nzcomms.co.nz. 118.149.151.121 121-151-149-118.nzcomms.co.nz. 45177 Vibe 45.64.48.2 cdns-02.as45177.net. 45179 SiteHost 103.250.234.202 103-250-234-202.static.webslice.co.nz. 45267 Lightwire 114.134.0.194 114-134-0-194.lightwire.co.nz. 132347 MikiPro 2404:ab00:6:1::6 132692 GlobiCom 103.18.58.198 vpn2.torguardvpnaccess.com. 133607 Web Connect 103.51.101.28 135069 Feenix 103.208.143.164 103-208-143-164.feenix.co.nz.
