![]() ![]() Once you’ve downloaded the disk image and dragged the program into your Applications folder, launch DynDNS Updater. ![]() Your choice here is largely a matter of taste (unless you’re going to be hosting a business Web site on your home Mac, in which case it’s also a question of marketing) the important thing is to choose a name you’ll remember. Dynamic DNS offers an extensive list of domain names, ranging from the bland ( ) to the quirky ( ) to the oddly specific ( ). This menu is where you choose the second part of your address, the domain name, which is everything after the first period. To enable a dynamically changing address, you pair a domain name provided by DynDNS with a host name you create. Fill in the name you want and then open the drop-down menu next to the host-name field. That can be anything you want, as long as someone else hasn’t registered it already. That address has two parts: The left-most part, which comes before a period preceding the domain name (the dmoren in ), is called the host name. Now it’s time to select your Mac’s plain-English Net address. Once you’ve created an account, log in with your new user name and password, click on My Services, and then click on Add Hostname to the right of the Host Services list in the middle. With DynDNS, that means going toĪnd clicking on Create Account to get started with a free account. The first thing you need to do is set up an account. This comprehensive list.) For this column, I’ll use DynDNS as an example, but the instructions are similar for other providers. The IP address update is also shown in the DDNS provider administration interface.Several companies offer dynamic DNS services. Kerio Control should update the DDNS records automatically and all the mapped services should be accessible. Unless a specific traffic rule is in place, it will use any of the interfaces available to determine this. Kerio Control uses a helper URL to determine the IP address. Note: If you don't know which option is the best, switch to the Detected public IP address. The real public IP address needs to be assigned to the selected interface. IP address configured on the interface - Kerio Control sends the IP address from the chosen interface to the DDNS provider.Detected public IP address - before sending the IP address to the DDNS provider, Kerio Control detects which IP address is used for access to the Internet.IP address configured on outgoing Internet interface - Kerio Control always sends the IP address from the Internet interface to the DDNS provider.If Kerio Control uses the multiple internet links mode (load balancing or failover) you can choose how to identify IP addresses for your DDNS provider:.Set a username and password for access to updates of the dynamic record.If DDNS supports wildcards, they can be used in the hostname. In the Update hostname field, type a DNS name.Select option Automatically update dynamic DNS service records with the firewall's IP address.In the Kerio Control administration interface, go to Remote Services > Dynamic DNS.Create an account at the following DDNS provider: ChangeIP, DynDNS, or No-IP.This request starts the update of DNS records of both names. If the IP address is changed, it is, therefore, possible to send a single request for an update of DNS records with the name *. For example, in DDNS there exist two hostnames, both linked to the public IP address of the firewall: fw. and. Some DDNS servers also allow concurrent updates of more records.The probability that the client receives a DNS response with an invalid (old) IP address is, therefore, very low. Dynamic DNS records use very short time-to-live (TTL) and, therefore, they are kept in the cache of other DNS servers or forwarders for a very short time.This keeps the DNS record for the particular IP address up-to-date and mapped services may be accessed by the corresponding hostname. If Kerio Control enables cooperation with dynamic DNS, a request to update the IP address in dynamic DNS is sent upon any change of the Internet interface's IP address (including switching between primary and secondary Internet connection). Note: To establish a successful working connection, you need to have Public IP address assigned to Kerio Control. ![]() You can register and select a free hostname for the domain, for example,. Kerio Control allows configuring Dynamic DNS for 3 different providers, such as DynDNS,, or. DDNS is a service providing the automatic update of the IP address in the DNS record for the particular hostname. ![]()
