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.

You can do a lot with A records, including using multiple A records for the same domain in order to provide redundancy. Additionally, multiple names could point to the same address, in which case each would have its own A record pointing to that same IP address. The DNS A record is specified by RFC 1035. A record format. If you plan to send from multiple domains, you should set up reverse DNS for at least one IP address per domain. It can take up to 48 hours for the records to verify after you upload them to your DNS host, so you will likely have to come back later to verify.

Cloudflare’s anycast is only for anycasting to the nearest CF datacenter, while the CF datacenter itself will only proxy traffic to the single IP address set up for the DNS zone in the dashboard (you can’t add multiple IP addresses to a single dns zone). Jul 31, 2018 · A DNS zone is a subset of the domain name system, often a single domain. A zone file contains the mappings between IP addresses and names within that subset, in the form of individual resource records that point to different aspects of the domain. Assuming you mean: Can a single name lookup result in multiple IPs for that name? It is possible in theory, but hardly ever used. And even if so, most client programs just use the first IP given, so it hardly ever gets sent out that way.

Simplified: an application queries the DNS and gets an IP address. 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.

A zone scope is a unique instance of the zone. A DNS zone can have multiple zone scopes, with each zone scope containing its own set of DNS records. The same record can be present in multiple scopes, with different IP addresses or the same IP addresses.
