Two other host names, along with famsuptasks.com, hubhoppers.com and repparo.com, also share IP numbers with studyzone.com.br.

Name Servers

studyzone.com.br uses two name servers for its delegation: b.sec.dns.br and c.sec.dns.br.

studyzone.com.br shares its NS records with other domains, for example brcs.com.br, vedantelinkseal.com.br, detudohomecenter.com.br and two others.

There is at least partial name server overlap between studyzone.com.br and other domains — bndt.com.br, smartplug.com.br, javali.com.br and two more among them.

These name servers are routinely deployed together with the name servers a.sec.dns.br.

The two host names b.sec.dns.br and c.sec.dns.br each have a pair of IP addresses: b.sec.dns.br has 200.192.232.11 and 2001:12f8:b:1::11, and c.sec.dns.br has 200.189.40.11 and 2001:12f8:9:1::11.

Mail Servers

Five mail servers handle studyzone.com.br: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com and two others.

There is at least a partial MX overlap between studyzone.com.br and other domains, including thinlineglobal.com, ns500754.ns500754.ns500671.ns500754.ns500704.ns500742.ns500704.ns500704.ns500688.ns500704.ns500671.ns500688.ns500291.ns500671.ns500666.ns500153.tenderladiesbz.com, ns500758.ns500759.ns500758.ns500759.ns500576.ns500576.ns500686.ns500576.ns500576.trackreceptor.com and two others.

These mail servers tend to appear in combination with mail servers alt3.aspmx.l.google.com, alt4.aspmx.l.google.com, aspmx2.googlemail.com and 3 others.
