Méthodes publiques

Méthode	Description
Lookup ( string hostname, DNSQType queryType, int timeout, List dnsServers ) : Heijden.DNS.DNSResponse	This method will wait until either the lookup completes or the timeout is reached before returning.
Lookup ( string hostname, DNSQType queryType, int timeout, List dnsServers, bool useCache, bool async ) : Heijden.DNS.DNSResponse
LookupAsync ( string hostname ) : Heijden.DNS.DNSResponse	Does a lookup on the DNSManager's currently cached entries. If not found it returns null indicating no information is currently available on the host while at the same time queueing a lookup for the DNSManager to do a lookup. Once the lookup has been completed the entry will be stored in cache and available for subsequent lookup requests. This approach to lookups is very useful for some SIP request situations. SIP has a built in retransmit mechanism so rather than hold up the processing of a SIP request while a DNS lookup is done the request can be ignored and in the time it takes for the SIP request retransmit the lookup can be done.
