Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4), or more complex newer alphanumeric IP addresses such as …
A DNS server with round-robin enabled will have multiple different A records, each with the same domain name but a different IP address.Each time the DNS server is queried, it sends the IP address to which it most recently responded with to the back of the queue, operating on a loop. One A Record, Multiple IP Addresses If this is the wrong place to ask this, please direct me to a better one. I was doing some DNS querying and I noticed that a particular FQDN has an A record which lists 4 addresses, the first three octets being the same with the last octet being 0, 1, 3, and 4 for the four addresses. Nov 02, 2017 · The link you include in your question goes into the technical details of how you can do this, but the reason for doing it is pretty simple. Say you have a website that you never want to go offline. A system called the Domain Name System, or DNS, associates names, like www.example.com, with the corresponding addresses. Your computer uses the DNS to look up domain names and get the associated IP address, which is used to connect your computer to the destination on the internet. - [Voiceover] And it goes a little something like this. - Hey
Then it connects to that IP address. If that connection fails, the application won't go back to the first step and query the DNS again, only if coded explicitly to do this. And querying a DNS server multiple time does not necessarily gives you different IP address. So in short, stock DNS cannot be used for load-balancing purposes. – karatedog

DNS Records Explained
Domain and IP bulk lookup tool allows to lookup domain, location, ISP and ASN for multiple hosts (IPs or domains) at once. It also supports lookup of MX or NS DNS records for multiple domains. This tool is commonly used for investigating IPs found in server logs.
Multiple IP addresses cannot be assigned to resources created through the classic deployment model. To learn more about Azure deployment models, read the Understand deployment models article. Scenario. A VM with a single NIC is created and connected to a virtual network. The VM requires three different private IP addresses and two public IP DNS works kind of like a phone book, looking up human-readable things like website names, and converting those to IP addresses. DNS does this by storing all that information on a system of linked DNS servers across the internet. Your devices need to know the addresses of DNS servers to which to send their queries. Jan 19, 2018 · NsLookup for Bulk of Servers\IP addresses Run NsLookup for Bulk of Servers\IP addresses instead of running it for individual host(s)If you have multiple hosts IP's that need to be identified instead of lookup multiple times upload the IP's in notepad and run below PS script.NsLookup can be used with multiple syntax's som Option 1: Use DNS to resolve into multiple IP addresses. For example: - If I make call from the UK machine, to the server.copmany.com - DNS to resolve this into UK IP address of the system in question. - If I make call from the US machine, to the server.copmany.com - DNS to resolve this into US IP address of the system in question. Feb 20, 2014 · DNS can hold multiple records for the same domain name. DNS can return the list of IP addresses for the same domain name. When a web-browser requests a web-site, it will try these IP addresses one-by-one, until it gets a response. These IP addresses should point at not application servers but at load-balancers / reverse-proxies.
