Analysis

IP Addresses

Eight IP numbers are pointed to by exercisechallenge.s3.amazonaws.com: 3.5.10.112, 16.15.207.29, 52.216.35.225, 52.216.42.161, 52.217.73.108, 52.217.81.220, 52.217.230.241 and 52.217.232.249.

Other host names, for instance s3-w.us-east-1.amazonaws.com, share IP numbers with exercisechallenge.s3.amazonaws.com.

Name Servers

exercisechallenge.s3.amazonaws.com delegates to four name servers: ns-328.awsdns-41.com, ns-674.awsdns-20.net, ns-1173.awsdns-18.org and ns-1620.awsdns-10.co.uk.

exercisechallenge.s3.amazonaws.com at least partially shares name servers with other domains, for instance discoverkokoro.com, warentest.org, d2grhvctvttt6.cloudfront.net, form-15g-declaration.com and pergosolutions.com.

Host names with two IP numbers: ns-328.awsdns-41.com points to 2600:9000:5301:4800::1 and 205.251.193.72; ns-674.awsdns-20.net points to 2600:9000:5302:a200::1 and 205.251.194.162; ns-1173.awsdns-18.org points to 2600:9000:5304:9500::1 and 205.251.196.149; ns-1620.awsdns-10.co.uk points to 2600:9000:5306:5400::1 and 205.251.198.84.
