DNS ActiveX control (skdns.ocx) allows developers to integrate the DNS (Domain Name Service) protocol message sending capability into their applications.
DNS ActiveX Control is compliant with RFC 1034 and RFC 1035.
DNS ActiveX Control can retrieve information about the host/domain by performing a general DNS lookup, or to list addresses in specified domain by performing an AFXR (special zone transfer) lookup. DNS ActiveX Control is capable of performing multiple general DNS lookups and/or multiple AFXR requests simultaneously.
It can request any of 41 different DNS record types: A, NS, MD, MF, CNAME, SOA, MB, MG, MR, NULL, WKS, PTR, HINFO, MINFO, MX, TXT, RP, AFSDB, X25, ISDN, RT, NSAP, NSAP_PTR, SIG, KEY, PX, GPOS, AAAA, LOC, NXT, EID, NIMLOC, SRV, ATMA, TKEY, TSIG, MAILB, MAILA, NAPTR, KX, CERT.
When loaded, DNS ActiveX Control automatically detects configured DNS servers.
DNS ActiveX Control can be used from any Windows-based applications development environment, including Visual Studio. The control comes with documentation, sample code, and working demo programs.
