IP Addresses

polyspace.org points to two IP numbers: 50.16.29.234 and 52.23.75.179.

steepestascent.com, www.mathworks.net.au, matlab.sg and two other host names share IP numbers with polyspace.org.

Name Servers

The DNS delegation for polyspace.org covers 4 name servers — ns-313.awsdns-39.com, ns-519.awsdns-00.net, ns-1131.awsdns-13.org and ns-1918.awsdns-47.co.uk.

There is at least partial name server overlap between polyspace.org and other domains — teachme-group.com, 11.134.15.in-addr.arpa, perflab-devops.com and two more among them.

These name servers tend to appear together with ns1-24-ap-southeast-2.ec2-rdns.amazonaws.com, ns2-24-ap-southeast-2.ec2-rdns.amazonaws.com, ns3-24-ap-southeast-2.ec2-rdns.amazonaws.com and three other name servers.

All four hostnames — ns-313.awsdns-39.com, ns-519.awsdns-00.net, ns-1131.awsdns-13.org and ns-1918.awsdns-47.co.uk — resolve to two IP numbers apiece: ns-313.awsdns-39.com to 205.251.193.57 and 2600:9000:5301:3900::1; ns-519.awsdns-00.net to 205.251.194.7 and 2600:9000:5302:700::1; ns-1131.awsdns-13.org to 205.251.196.107 and 2600:9000:5304:6b00::1; ns-1918.awsdns-47.co.uk to 205.251.199.126 and 2600:9000:5307:7e00::1.
