Analysis

IP Addresses

prosys.com.br resolves to just one IP address, 191.252.4.20.

Two other host names, along with harpia.com.br, catral.com.br and webguest.com.br, also share IP numbers with prosys.com.br.

Name Servers

prosys.com.br carries NS records delegating to ns1.locaweb.com.br, ns2.locaweb.com.br and ns3.locaweb.com.br.

prosys.com.br partially shares its NS delegation with several other domains, including 58.76.201.in-addr.arpa, 184.252.191.in-addr.arpa, northbio.com.br and two others.

ns1.locaweb.com.br, ns2.locaweb.com.br and ns3.locaweb.com.br are three hostnames that each resolve to a pair of IP addresses: ns1.locaweb.com.br to 186.202.8.254 and 2804:218:7000:0:186:202:8:254, ns2.locaweb.com.br to 187.45.248.254 and 2804:218:7001:0:187:45:248:254, and ns3.locaweb.com.br to 189.126.101.254 and 2804:218:7002:0:189:126:101:254.

Mail Servers

prosys.com.br uses three mail servers — mx.a.locaweb.com.br, mx.b.locaweb.com.br and mx.jk.locaweb.com.br.

There is at least a partial MX overlap between prosys.com.br and other domains, including ruraltotal.com.br, m4rcio.com, tiptoeyjoey.com and two others.

These mail servers often co-occur with the mail servers mx.core.locaweb.com.br.

mx.a.locaweb.com.br points to 186.202.4.42; mx.b.locaweb.com.br points to 177.153.23.242; mx.jk.locaweb.com.br points to 200.234.204.130 — each hostname maps to exactly one IP address.
