When creating a load balancer the input for the origins can be an IP or domain, in the case of using a domain pointing to multiple IP addresses, how the traffic is balanced or what algorithm is used (round-robin, lastconn?
For example, if using 2 origins:
a.example.org --> resolves to (10.0.0.1, 10.0.0.2) with TTL of 60s b.example.org --> resolves to (10.0.0.3, 10.0.0.4)
Will the load balancer use round-robin for the origins so that when hits for example
a.example.org will dispatch traffic from both endpoints (10.0.0.1 & 10.0.0.2) and obey the defined TTL or it will only use the last connected server and impose a fixed TTL?
