Analysis
Hierarchy
computationalthinking.org serves as the parent of www.computationalthinking.org.
Name Server Role
computationalthinking.org serves as a name server for itself — computationalthinking.org is its own authoritative name server.
The name servers wri-dns2.wolfram.com and wri-dns3.wolfram.com are often paired with computationalthinking.org.
IP Addresses
computationalthinking.org points to a single IP number: 140.177.52.200.
Additional host names — computationalknowledge.org.uk, integrals.com, spikeyspot.com and two others — share IP numbers with computationalthinking.org.
Name Servers
computationalthinking.org is delegated to three name servers: computationalthinking.org, wri-dns2.wolfram.com and wri-dns3.wolfram.com.
computationalthinking.org has at least partial name server overlap with other domains, such as wolframblockchainlabs.com, wolfram-science.net, wolfram.com and two others.
It is common to find these name servers paired with the name servers dns-master.wolfram.com, wri-dns0.wolfram.com, wri-dns1.wolfram.com and ns6.wolfram.com.
computationalthinking.org, wri-dns2.wolfram.com and wri-dns3.wolfram.com each resolve to a single IP address: computationalthinking.org resolves to 140.177.52.200, wri-dns2.wolfram.com resolves to 140.177.10.23 and wri-dns3.wolfram.com resolves to 140.177.10.19.
Mail Servers
computationalthinking.org has two mail servers: mx1.wolfram.com and mx2.wolfram.com.
computationalthinking.org shares the same mail server setup as other domains, including wolframresearch.cn, nksonline.org, wolframdatasummit.org and two others.
computationalthinking.org has mail servers in common with other domains — for example wolframphysics.org and tgjb.com.
mx1.wolfram.com directs to 140.177.10.56 and mx2.wolfram.com directs to 140.177.10.59; each host name points to exactly one IP number.
