Greetings,my problem isI need to senda UDP packetto apublic addresstypeadress.no-ip.biz. If i send a packet to the IP in the format 212.123..... its works, but if i use the format "adress.no-ip... dont send nothing. I need to send it with the letters format because i have a internet dynamic adress. The solution is to work with java.net an datagramsocket?
