Analysis

IP Addresses

linked.cc directs to four IP numbers, which are 104.21.54.84, 172.67.136.252, 2606:4700:3031::6815:3654 and 2606:4700:3034::ac43:88fc.

Two other host names, along with stayhelperly.com, tryflux.com and frontrangelocksmith.com, also share IP numbers with linked.cc.

Name Servers

Two name servers handle the delegation for linked.cc: art.ns.cloudflare.com and uma.ns.cloudflare.com.

linked.cc shares its NS records with other domains, for example carolinaphone.com, hepsidolgu.com, lords.ws and two others.

There is at least partial name server overlap between linked.cc and other domains — dawnofthedawg.com, thistleandthreaddesign.com, hairbarnyc.com and two more among them.

These name servers are routinely deployed together with the name servers lara.ns.cloudflare.com.

DNS names with 6 IP addresses:

art.ns.cloudflare.com resolves to 108.162.193.102, 172.64.33.102 and 173.245.59.102 among others, with 3 other IP addresses in total.

uma.ns.cloudflare.com resolves to 108.162.192.146, 172.64.32.146 and 173.245.58.146 among others, with 3 other IP addresses in total.

Mail Servers

Incoming mail for linked.cc is delivered via three mail servers: mx1.larksuite.com, mx2.larksuite.com and mx3.larksuite.com.

There is at least a partial MX overlap between linked.cc and other domains, including 6699.me, gaganode.com, x.me and two others.

Hostnames that map to three IP numbers:

The hostname mx3.larksuite.com points to 18.139.153.173, 101.126.58.223 and 122.14.230.154.

Host names that point to one IP address:

The hostname mx1.larksuite.com resolves to 18.139.153.173.

The hostname mx2.larksuite.com resolves to 18.139.153.173.

Each of mx3.larksuite.com, mx1.larksuite.com and mx2.larksuite.com resolves to 18.139.153.173.
