@a19cf39a: Regarding your first question, you can have multiple A records for a single domain name. This is often used for load balancing or redundancy purposes. However, having too many A records can cause issues with DNS resolution and may lead to slower performance or even DNS errors. It's generally recommended to keep the number of A records to a reasonable amount.

Regarding your second question, "Proxies" means that the DNS resolution is being handled by a proxy server, while "DNS only" means that the DNS resolution is being handled directly by the DNS server. In other words, "Proxies" indicates that there is an additional layer between the client and the DNS server, which may provide additional features such as caching or load balancing.
