Can domain have multiple A records?
The value of an A record is always an IP address, and multiple A records can be configured for one domain name.
Can you have multiple Cname records for one domain?
2 Answers. Multiple CNAME records for the same fully-qualified domain name is a violation of the specs for DNS. Some versions of BIND would allow you to do this (some only if you specified the multiple-cnames yes option) and would round-robin load-balance between then but it’s not technically legal.
Do browsers cache IP addresses?
If your browser has already been to this website recently, it may already know what the IP address for the website in question is, and have that value cached. Browser caches don’t usually last long, so it would’ve been a recent visit.
How can a domain have multiple IP addresses?
Yes, that is possible, and will need to be two A records. This is called Round-Robin DNS. Clients will semi-randomly use one of the two addresses. The certificate is not tied to the IP address, only to the domain name,so if it is installed on both servers, there should be no issues with SSL.
What happens when you have multiple records on a domain?
If you have multiple A records on a domain then when your nameserver requests the IP for the domain you typed into your browser, it’ll request one from the SOA. It could be any of those A records. Then it passes it along.
Can a browser try the other a record?
Yes, most browsers from the last 5-10 years will try the other A records if one fails to respond. This is sometimes called “browser retry” or “client retry” apparently.
Is it possible to have multiple a Records?
And this would be very helpful to create a fault tolerant website. Yes, most browsers from the last 5-10 years will try the other A records if one fails to respond. This is sometimes called “browser retry” or “client retry” apparently.
Is it possible to have two DNS records?
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.
