AI analysis

opnet.com is a parent of nsba.opnet.com, coloftp.opnet.com, www.opnet.com, smtp-hq2.opnet.com, nsc-forum.opnet.com and several other host names.

opnet.com points to a single IP number: 69.25.34.6.

Other host names, for instance colowww.opnet.com, share IP numbers with opnet.com.

opnet.com is delegated to four name servers: dns-01.riverbed.com, dns-02.riverbed.com, dns-03.riverbed.com and dns-04.riverbed.com.

opnet.com at least partially shares name servers with other domains, for instance networkphysics.eu, riverbedtechnologyisterrible.com, riverbedtechnologythinkslow.com, riverbedsko.com and fastpage.org.

Host names with two IP numbers:

dns-01.riverbed.com points to: 2600:9000:5303:ec00::1 and 205.251.195.236.

dns-02.riverbed.com points to: 2600:9000:5304:e900::1 and 205.251.196.233.

dns-03.riverbed.com points to: 2600:9000:5301:a300::1 and 205.251.193.163.

dns-04.riverbed.com points to: 2600:9000:5306:5100::1 and 205.251.198.81.

opnet.com is handled by a single mail server, riverbed-com.mail.protection.outlook.com.

opnet.com uses the same mail server configuration as other domains, such as riverbedtechnology.com, aternity.com, mazunetworks.com, rvbdit.net and riverbed.com.

riverbed-com.mail.protection.outlook.com resolves to eight IP addresses: 2a01:111:f403:c801::1, 2a01:111:f403:c902::16, 2a01:111:f403:c946::2, 2a01:111:f403:c946::3, 52.101.9.11, 52.101.9.12, 52.101.10.16 and 52.101.40.6.
