Can you have multiple A records pointing to same IP?

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.

When to use a logical hostname instead of an IP address?

When possible, use a logical DNS hostname instead of an ip address, particularly when configuring replica set members or sharded cluster members.
