Can you have two A records pointing to different IPS?
No, an A record can only point to one IP address.
Can a server have 2 IPS?
Yes you can have more than one IP address when using a single Network Card. Setting this up is different in each Operating System, but may involve creating a new Network Interface. This can look like a unique connection but will be using the same Network Card behind the scenes.
How many IPS can an EC2 instance have?
When we launched the Elastic Network Interface (ENI) feature last December, you were limited to a maximum of two ENI’s per EC2 instance, each with a single IP address. With today’s release we are raising these limits, allowing you to have up to 30 IP addresses per interface and 8 interfaces per instance on the m2.
Can a DNS lookup result in multiple IPs?
So … yes and no. In general a single DNS lookup tends to only result in a single IP. But that IP might change depending on factors defined by how the DNS is implemented.
Can a DNS host have more than one IP address?
Verify your account to enable IT peers to see that you are a professional. On the DNS server the only entries for the first network card are for the correct IP address. There are no references to the second NIC in the forward or reverse lookup zones. It is working now, but still curious where the DNS server was caching the previous one.
How does a DNS server choose the Order of the IPS?
DNS servers and DNS resolvers randomly choose the order of the list of IPs – even though you might configure it a certain way on your DNS Server hosting the zone, resolvers will flip it. So you can’t force all connections to go through a certain link and use the 2nd link for failover.
Can a single a record have multiple IP’s?
Yes you can have multiple IP’s for the same A record. There’s a few problems with this if used for redundancy purposes… DNS servers and DNS resolvers randomly choose the order of the list of IPs – even though you might configure it a certain way on your DNS Server hosting the zone, resolvers will flip it.
