I use DynDNS account and I find this information, if I need update via HTTP but not HTTPS the expression is require (ssl.hhtps) or anothrer, thank you

I beleive it will work with https. Bonus is that it's much more secure than http.

Just tested this 

Code:

http://username:password@members.dyndns.org/nic/update?hostname=yourhostname&myip=ipaddress&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG
https://username:password@members.dyndns.org/nic/update?hostname=yourhostname&myip=ipaddress&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG

And both gives the same correct result: badauth

When updating any dynamic DNS service make sure you are sending update only when the IP is changed. Many will ban/suspend the account if the update is to frequent. Use the sample from the first link to determine if the IP was changed - only then send the update with the second sample. By this method you can get the fastest possible refresh without risking a much longer delay.
