The ExLookupDN COM object is a DNS (Domain Name Service) component that can be used for network diagnosing, troubleshooting, and monitoring. The ExLookpNS allows developers to integrate the DNS protocol message sending capability into their applications. The ExLookupNS's object model is rich, flexible and very intuitive. For instance, the statement .Query('devx.com').MailExchange gives you the list of mail servers:). It is fully compliant with RFC 1034, RFC 1035, RFC 1876. It can request any of the following DNS record types: A(Address), NS(NameServer), MD(MailDestination), MF(MailForwarder), CNAME(CanonicalName), SOA(ZoneOfAuthority), MB(MailBoxDomainName), MG(MailbogGroupMember), MR(MailRenameDomainName), WKS(WellKnwonService), PTR(DomainNamePointer), HINFO(HostInformation), MINFO(MailInformation), MX(MailExchange), LOC(Location). When created, the ExLookupNS component automatically detects configured DNS servers.
