Analysis

IP Addresses

Eight IP numbers are pointed to by depth-first.s3.amazonaws.com: 16.15.212.223, 16.15.228.163, 16.15.229.198, 16.15.253.110, 52.217.169.193, 54.231.130.17, 54.231.170.161 and 54.231.224.121.

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

Name Servers

depth-first.s3.amazonaws.com is delegated 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.

depth-first.s3.amazonaws.com at least partially shares its name servers with other domains, for instance northsaanichfire.ca, dk.freelancer.com, helpbaji.live, twic.it and d2yhzk1gkn7bw8.cloudfront.net.

Host names with two IPs: 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.
