Does the DNS service support weighted polling?

Excuse me!
When domain name A records are resolved to multiple IP addresses at the same time, is there a weighting function?

For example:
Record 1: www -> 127.0.0.1
Record 2: www -> 127.0.0.2
Record 3: www -> 127.0.0.3

127.0.0.1 has a weight of 30
127.0.0.2 has a weight of 10
127.0.0.3 has a weight of 60

When there is a DNS query request for www,
30% chance of resolving to 127.0.0.1,
10% chance of resolving to 127.0.0.2,
60% chance of resolving to 127.0.0.3

May I ask, does your company’s DNS have this function?
