If both IP addresses are available traffic will be split 50/50 between 1.2.3.4 and 1.2.3.5.2 I Simple DNS Plus Table of Contents Part I Welcome 4 Part II How to Get started Host a domain. Now, if 1.2.3.4 is not available 100% of traffic will be sent to 1.2.3.5, and if 1.2.3.5 is not available 100% of traffic will be sent to 1.2.3.4. We are configuring the primary IP address of 1.2.3.5 to be monitored on HTTP port 80 and failover to the IP address 1.2.3.4 if the primary is not available.

The current IP will remain 1.2.3.5 until it is manually edited back to 1.2.3.4. This means that DNS Failover will not revert traffic back to the primary IP address automatically. We have also enabled the “Turn off auto-failover after first failure” feature with a checkmark. In addition, the webserver must reply with a 200 response code. All these criteria must be met for the IP to be considered online.

The system will query and look for the string of UP in the first 1KB of text on that page. We have also added a file and string to query for in the HTTP configuration (this is only example data), these fields are optional with an HTTP or HTTPS configuration.

This is the full hostname of the monitored system. In the example here we are configuring the primary IP address of 1.2.3.4 to be monitored on HTTP port 80 and failing over to the IP address 1.2.3.5 if the primary is not available.į.Enter the fully qualified domain name of the system you are monitoring. Configure a port and protocol to monitor based on what criteria you want to confirm is reachable on your server. The lower the sensitivity level, the more confirmations the monitoring servers will make.Į. Low Sensitivity performs nine immediate checks. Medium Sensitivity (which is the default) performs six immediate checks. High Sensitivity means fewer checks, three checks are made in immediate succession of one another to confirm the status of the server. Select a maximum number of emails you would like to receive regarding each system monitoring and/or failover eventĭ.Select a Sensitivity Level – The sensitivity option in DNS Failover allow you to specify different numbers of checks the monitoring locations will make against the IP. The default notification is to the Account Owner which is the email address on file for the account (you can view this under the Config – Users menu).Ĭ. Select your contact list to be notified of IP statuses or changes – We select the one we created. Provide a System Description – this will be included in the notification you receive so you know which system the notification is for.ī. Enable System Monitoring and/or DNS FailoverĪ. If an A record does not already exist for the desired name, then under “A Records” click the plus sign to add a new A record.Ĩ. Select a domain from either the “Recently Updated Domains” box, or start typing the domain name in the textbox on the “Select Domain” tab.

The steps to configure DNS Failover are as follows: You can specify up to 5 IP addresses for each of your hostnames. As soon as your primary server fails to respond from at least two different geographic monitoring locations, your DNS is instantly updated on all DNS Made Easy name servers globally to point a secondary IP address as long as it does respond on the same port and protocol configured. You can set up the monitoring servers to check if your service is running on either TCP, UDP, HTTP, or HTTPS protocols, and on any port. DNS Made Easy’s monitoring nodes check your primary IP address on a 2 to 4-minute monitoring window. Here is how the DNS Failover services work:ĭNS Failover services are configured on A records which point to IP addresses. This service can also be used to migrate traffic between redundant internet connections. This is done by moving DNS traffic to another IP address that you have running at another location. The DNS Failover service from DNS Made Easy is used to keep sites and web services online in the event of system or network issues.
