Analysis

IP Addresses

recursive.co maps to four IP numbers: 2606:4700:3033::6815:f12, 2606:4700:3034::ac43:a106, 104.21.15.18 and 172.67.161.6.

Other host names, for instance asia-tone.com, www.psperu.com, paio.gr, phonehelp.fr and szykyy120.com share IP numbers with recursive.co.

Name Servers

Two name servers clint.ns.cloudflare.com and reza.ns.cloudflare.com are delegated to recursive.co.

recursive.co uses the same name server configuration as other domains, such as fujoceeee.jp, bp2tpontianak.com, nativecaribbean.com, r34(0x706f726e).net and ancarat.com.

recursive.co at least partially shares name servers with other domains such as channelindex.co.uk, outreachai.co, nilamauto.com, delinate.com and 250099c.com.

these name servers are commonly used with the name servers wally.ns.cloudflare.com.

Host names with six IP numbers: Host name clint.ns.cloudflare.com points to 2606:4700:58::adf5:3b5a, 2803:f800:50::6ca2:c15a, 2a06:98c1:50::ac40:215a, 108.162.193.90, 172.64.33.90 and 173.245.59.90; host name reza.ns.cloudflare.com points to 2606:4700:50::adf5:3ad9, 2803:f800:50::6ca2:c0d9, 2a06:98c1:50::ac40:20d9, 108.162.192.217, 172.64.32.217 and 173.245.58.217.

Mail Servers

recursive.co is handled by four mail servers: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com and alt3.aspmx.l.google.com.

recursive.co shares mail servers with other domains at least in part, for instance clickandbook.net, welldonemaintenance.com, ns500698.ns500758.ns500759.ns500759.ns500698.ns500759.ns500736.ns500735.ns500698.ns500698.ns500708.ns500708.ns500708.ns500619.ns500576.ns500652.ns500576.trackreceptor.com, ns500698.ns500698.ns500759.ns500698.ns500759.ns500735.ns500736.ns500576.ns500698.ns500708.ns500708.ns500619.ns500576.ns500619.ns500619.trackreceptor.com and net-delivery-node.com.

These mail servers are often used together with alt4.aspmx.l.google.com, aspmx2.googlemail.com, aspmx3.googlemail.com, aspmx4.googlemail.com and aspmx5.googlemail.com.

Host names with two IP numbers:
