Analysis

IP Addresses

sci2.org directs to four IP numbers, which are 104.21.61.239, 172.67.216.252, 2606:4700:3033::6815:3def and 2606:4700:3035::ac43:d8fc.

Two other host names, along with szekhely.com, www.vanleeuwen-stucadoors.nl and zuidai.cn, also share IP numbers with sci2.org.

Name Servers

Two name servers handle the delegation for sci2.org: johnathan.ns.cloudflare.com and rosa.ns.cloudflare.com.

sci2.org shares its NS records with other domains, for example ast-deti.ru, parnian.com, remax-wissen.de and two others.

There is at least partial name server overlap between sci2.org and other domains — ubowoye.top, liaochenggangguan.com, slotspalaceopinie.pl and two more among them.

These name servers tend to appear in combination with the name servers darl.ns.cloudflare.com, martha.ns.cloudflare.com, stephane.ns.cloudflare.com and emely.ns.cloudflare.com.

DNS names with 6 IP addresses:

johnathan.ns.cloudflare.com resolves to 108.162.195.44, 162.159.44.44 and 172.64.35.44 among others, with 3 other IP addresses in total.

rosa.ns.cloudflare.com resolves to 108.162.192.228, 172.64.32.228 and 173.245.58.228 among others, with 3 other IP addresses in total.
