Analysis

IP Addresses

Eight IP numbers are pointed to by ntp.dev: 2a04:4e42::311, 2a04:4e42:200::311, 2a04:4e42:400::311, 2a04:4e42:600::311, 151.101.1.55, 151.101.65.55, 151.101.129.55 and 151.101.193.55.

other host names for instance koat.com, kcra.com, medco-athletics.com, aspectsofkingspark.com and openstreetmap.se share IP numbers with ntp.dev.

Name Servers

ntp.dev is delegated to five name servers: anyns.pch.net, a.ns.bitnames.com, b.ns.bitnames.com, c.ns.bitnames.com and d.ns.bitnames.com.

ntp.dev at least partially shares name servers with other domains, for instance ntppool.net, ecorace.nl, quadnine.org, quad9.net and 46.102.66.in-addr.arpa.

These name servers are commonly used with the name servers ns2.pch.net, ns1.pch.net, ns3.pch.net, ns1.us.bitnames.com, ns1.eu.bitnames.com, ns2.eu.bitnames.com, ns2.us.bitnames.com, ns3.us.bitnames.com and ns.anycast.woodynet.net.

Host names with four IP numbers:
