sch.org is a parent of hostmaster.sch.org, chromium.sch.org, iron.sch.org, copper.sch.org and mobility.sch.org, plus a few other host names.

IP Addresses

sch.org resolves to one IP number: 104.17.70.73.

Other host names, for instance magnoliaisd.org, stjoe.sch.org, greenlocalschools.org, usd385.org and fcschools.net share IP numbers with sch.org.

Name Servers

sch.org's delegation uses two name servers: ns1.hover.com and ns2.hover.com.

sch.org uses the same name server setup as other domains, such as bassan.org, iputils.net, lux22.com, theprivacyblog.com and mcabeemedical.com.
