C# Class Ipop.Dht.DhtDns

This class provides the ability to lookup names using the Dht. To add a name into the Dht either add a Hostname node into your AddressData node inside the IpopConfig or use another method to publish to the Dht. The format of acceptable hostnames is [a-zA-Z0-9-_\.]*.ipop (i.e. must end in .ipop)

Method Description
AddressLookUp ( String name ) : String

Called during LookUp to perform translation from hostname to IP. If an entry isn't in cache, we can try to get it from the Dht. Throws an exception if the name is invalid and returns null if no name is found.
DhtDns ( MemBlock ip, MemBlock netmask, string name_server, bool forward_queries, IDht dht, String ipop_namespace ) : Brunet

Create a DhtDns using the specified Dht object
NameLookUp ( String IP ) : String

Called during LookUp to perfrom a translation from IP to hostname. Entries get here via the AddressLookUp as the Dht does not retain pointer lookup information.
