You can have multiple A records for a single domain name. This is known as round-robin DNS, where multiple IP addresses are assigned to a single domain name and the DNS server rotates through the IP addresses in a round-robin fashion.
However, having too many A records can cause issues with DNS resolution. This is because DNS servers have a limit on the size of their response packets. If the response packet for a DNS query exceeds this limit, it can cause issues with DNS resolution. Additionally, having too many A records can also cause issues with load balancing, as the DNS server may not be able to effectively rotate through all the IP addresses.
It's generally recommended to have no more than 4-5 A records for a single domain name to avoid these issues.
