AspDNS V2.7

AspDNS can do forward and reverse DNS lookups returning either the IP address or the host name. Two methods are provided: DNSLookup(hostname - string) e.g. DNSLookup("mailhost.anyhost.com") The return value is a string with the IP address of the hostname. Failure is indicated by an empty string. ReverseDNSLookup(IPAddress - string) e.g. ReverseDNSLookup ("255.255.255.0") If the IP address is found in the DNS the return value is the hostname.
