How long does it take for DNS records to propagate?

DNS Propagation Time There’s no concrete answer for this, but typically DNS propagates within a few hours, though it can take as long as 72. The timeframe for propagation depends on several factors, including your internet service provider (ISP), your domain’s registry, and the TTL values of your DNS records.

Can DNS returns multiple IP addresses?

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. Web-application servers should be stateless to make the job of load-balancers easier.

What happens when a DNS server goes down?

As soon as a server goes down, the DNS server should automatically switch the DNS A record to list the IP address for the working server first. When DNS resolvers come back to request the IP address for the site, they receive the updated IP address, and route the user to the redundant server.

How long does it take for Cloudflare DNS to update?

Can you have more than 1 a record in DNS?

2 Answers. Yes you can. It is called round-robin DNS, and the browser just chooses one of them randomly. It is a well used method of getting cheap load balancing, but if one host goes down, users will still try to access it.

How do I trigger DNS propagation?

However, there is a simple way to speed up DNS propagation:

1. Define or modify an A record that points your hostname to the new destination IP address.
2. Set a minimal TTL for that DNS record—we recommend 5 minutes. Below that, many ISPs might ignore the TTL and retain the old record in cache.
