DNS delegation of sts.com.br updated: May 23, 2013 6:37:11 AM
We pick f.root-servers.net, one of the 13 root servers (1), and ask it about sts.com.br and learn that br is delegated to six name servers (2), so we ask f.dns.br where we learn that sts.com.br is delegated to four name servers, including ns3.outmirror.com.br (3), so we ask that one and get the following answer:
Sts.com.br is a domain controlled by four domain name servers at outmirror.com.br. Two domain name servers have the same IP number. Two of them are on the same IP network. Incoming mail for sts.com.br is handled by two mail servers at m3corp.com.br. Both are on different IP networks.
