Analysis

IP Addresses

Five IP numbers are pointed to by em.docker.com: 104.17.70.206, 104.17.71.206, 104.17.72.206, 104.17.73.206 and 104.17.74.206.

Other host names, for instance mkto-sj250009.com, mkto-sn010215.com, mkto-sjf0159.com, mkto-ab070176.com and mkto-ab200043.com share IP numbers with em.docker.com.

Name Servers

Two name servers ns1.marketo.com and ns2.mktdns.com handle delegation for em.docker.com.

em.docker.com uses the same name server setup as other domains, for example mkto-l0137.com, mkto-ab090179.com, mkto-ab010087.com, mkto-sj100039.com and mkto-sj140203.com.

em.docker.com partially shares name servers with other domains; examples include mkto-sj070011.com, mkto-sjf0044.com, mkto-sj130165.com, mkto-sj310102.com and mkto-sj200036.com.

these name servers are commonly used with the name servers ns3.marketo.co.uk.

Host names with one IP number: The host name ns1.marketo.com points to 199.15.213.1 and the host name ns2.mktdns.com points to 199.15.215.252.
