start.io is a parent of mail.start.io and support.start.io.

start.io points to two IP numbers: 2a04:4e42:79::820 and 146.75.39.52.

Other host names such as dualstack.t.sni.global.fastly.net and ipv6.instructables.map.fastly.net share IP numbers with start.io.

start.io is delegated to four name servers: dns1.p09.nsone.net, dns2.p09.nsone.net, dns3.p09.nsone.net and dns4.p09.nsone.net.

start.io at least partially shares name servers with other domains, for instance fioole.com, manbearpig.com, kpixtv.com, www-updates.com and habanaaustin.com.

These name servers are commonly used together with the name servers ns0004.secondary.cloudflare.com, ns0243.secondary.cloudflare.com, ns01.squarespacedns.com, ns02.squarespacedns.com, ns03.squarespacedns.com, ns04.squarespacedns.com, ns5.dnsmadeeasy.com, ns1-42.azure-dns.com, ns4-42.azure-dns.info and ns2-42.azure-dns.net.

Host names with two IP numbers:

dns1.p09.nsone.net points to: 2620:4d:4000:6259:7:9:0:1 and 198.51.44.9.

dns2.p09.nsone.net points to: 2a00:edc0:6259:7:9::2 and 198.51.45.9.

dns3.p09.nsone.net points to: 2620:4d:4000:6259:7:9:0:3 and 198.51.44.73.

dns4.p09.nsone.net points to: 2a00:edc0:6259:7:9::4 and 198.51.45.73.

start.io is handled by a single mail server, start-io.mail.protection.outlook.com.

start-io.mail.protection.outlook.com resolves to eight IP addresses: 2a01:111:f403:ca04::b, 2a01:111:f403:ca04::d, 2a01:111:f403:ca09::9, 2a01:111:f403:ca09::b, 52.101.68.0, 52.101.68.15, 52.101.73.19 and 52.101.73.24.
