Can a DNS A record have multiple IP addresses?
In either mode, a DNS A record must be defined with more than one IP address (known as DNS A record failover). The first IP address should point to the default, production server, and the other IP addresses should point to identical (or frequently synchronized) redundant servers.
Can an A record point to two IP addresses?
You can do a lot with A records, including using multiple A records for the same domain in order to provide redundancy and fallbacks. 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.
What happens when a zone contains two Cname records with the same name?
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.
Can an A record point to another domain?

Can a DNS host have more than one IP address?
The DNS server has an Host entry for each NIC. We’ll say it’s ServerA 192.168.0.10 and ServerA-Alt 192.168.1.10. You can ping either ip address from their corresponding network. The problem is that on the DNS server there is only one record for ServerA, but it is responding with both IP addresses using round robin.
Can a device have more than one DNS record?
you can have multiple A records for one device. all this means is that it can be referenced with more than one name. This is often used if a machine hosts more than one service or if the machine is a web server. for example. one web server will host many pages, but each page will have a unique dns record name all pointing to the same IP
Can you have multiple records with the same IP address?
You can have multiple A records using the same name that point to different IP addresses, for example: test.domain.com – 192.168.1.5. test.domain.com – 192.168.10.5. Anyone connecting to test.domain.com would then get either one of these two IP addresses.
Why is my DNS server responding with two IPS?
