Feb 20, 2014 · Click DNS on the left-hand menu and add a new domain name pointing to a load-balancer droplet from the previous step. Add a new A Records: Once you are on the next step, click “Add Record” on the upper-hand side and create a new A record, with the IP address of the other load-balancer droplet.
For advanced DNS load balancing techniques, see . Advanced DNS traffic management using the BIG-IP LTM, on page 2-1. Overview of DNS. At the most basic level, Domain Name System, or DNS as it is commonly known, is an Internet service that maps domain names into IP addresses and is an essential component of any network. There are two types of DNS About Global Server Load Balancing Introducing BIG-IP DNS BIG-IP®DNS(formerlyGTM™)isasystemthatmonitorstheavailabilityandperformanceofglobal The following are two possible ways used load balance mail servers using DNS: Define multiple MX records with the same priority; Define multiple A records with the same name and different IP addresses MX records, DNS and how emails are routed: Definitely use the multiple NS records, as TCP becomes more common for DNS just let it load-balance itself. Re-inventing the wheel is painful for a reason. – cpt_fink Feb 18 '15 at 4:34 Multiple DNS servers do offer redundancy and prevent total failure, but a downed DNS server would still cause name resolution delays. – 200_success Feb 18
DNS load balancing is the practice of configuring a domain in the Domain Name System (DNS) such that client requests to the domain are distributed across a group of server machines. A domain can correspond to a website, a mail system, a print server, or another service that is made accessible via the Internet.
The console prepends dualstack. to the DNS name. When a client, such as a web browser, requests the IP address for your domain name (example.com) or subdomain name (www.example.com), the client can request an IPv4 address (an A record), an IPv6 address (a AAAA record), or both IPv4 and IPv6 addresses (in separate requests). Here are the configuration methods of Load Balance function on TP-Link EAP/Omada Controller: Go to Access Points. Choose one of the EAP that you want to enable Load balance on. Then select Configuration->Load Balance->Enable Max Associated Clients, RSSI Threshold and click Apply. You can set Load Balance function in 2.4G and 5G radio separately. This is usually a Load Balancing VIP and not a DNS service. Users submit a DNS query to the NetScaler DNS VIP. NetScaler then finds a GSLB vServer that matches the DNS query. NetScaler then returns the IP address of one of the bound GSLB Services. In other words, the VIP you created to load balance DNS is separate from the GSLB configuration.
When you have deployed multiple instances of an application, you can use DNS policy to balance the traffic load between the different application instances, thereby dynamically allocating the traffic load for the application. Example of Application Load Balancing. Following is an example of how you can use DNS policy for application load balancing.

Example of Application Load Balancing. Following is an example of how you can use DNS policy for application load balancing. Round-robin DNS is often used to load balance requests among a number of Web servers. For example, a company has one domain name and three identical copies of the same web site residing on three servers with three different IP addresses. The DNS server will be set up so that domain name has multiple A records, one for each IP address. The loadbalance will act as a round-robin DNS load balancer by randomizing the order of A, AAAA, and MX records in the answer. See Wikipedia about the pros and cons of this setup. It will take care to sort any CNAMEs before any address records, because some stub resolver implementations (like glibc) are particular about that.
