opto.com is a parent of members.opto.com, web.opto.com and www.opto.com.

opto.com points to two IPs: 15.156.139.114 and 15.223.23.206.

Other host names, for example, ec2-15-223-23-206.ca-central-1.compute.amazonaws.com share IP numbers with opto.com.

opto.com is delegated to four name servers: ns-75.awsdns-09.com, ns-676.awsdns-20.net, ns-1154.awsdns-16.org and ns-1860.awsdns-40.co.uk.

opto.com at least partially shares name servers with other domains such as studiopastorello.com, shogakukan.net, eppyarn.co.jp, agiletripsolutions.com and businessbarometer.ie.

These name servers are often used together with ns-766.awsdns-31.net, ns-336.awsdns-42.com, ns-1701.awsdns-20.co.uk, ns3.vortala.com, ns4.vortala.com, ns5.vortala.com, ns6.vortala.com, ns-1943.awsdns-50.co.uk, ns-1399.awsdns-46.org and ns-1363.awsdns-42.org.

Host names with two IP numbers:

ns-75.awsdns-09.com points to 2600:9000:5300:4b00::1 and 205.251.192.75

ns-676.awsdns-20.net points to 2600:9000:5302:a400::1 and 205.251.194.164

ns-1154.awsdns-16.org points to 2600:9000:5304:8200::1 and 205.251.196.130

ns-1860.awsdns-40.co.uk points to 2600:9000:5307:4400::1 and 205.251.199.68

opto.com is handled by four mail servers: mx-cluster-ca-fallback.hornetsecurity.com, mx-cluster-ca01.hornetsecurity.com, mx-cluster-ca02.hornetsecurity.com and mx-cluster-ca03.hornetsecurity.com.

opto.com shares mail servers with other domains at least in part, for instance navettecorpo.com, jurisconseil.com, sinkflo.com, manuvic.com and syscomak.com.

these mail servers are commonly used alongside the mail servers mx14a.antispameurope.com.
