I am prometheus deployment and my instance label showing ipaddress instead of hostname.

node_cpu_seconds_total{cpu="0", instance="10.0.28.11:9100", job="node", mode="idle"}

I want to change instance with hostname like following example

node_cpu_seconds_total{cpu="0", instance="server1:9100", job="node", mode="idle"}

I am using following method to replace label but I have 100s of nodes and that is not a best way. does prometheus has better way to replace instance ip with hostname?

- job_name: node
  static_configs:
  - targets:
    - server1:9100
    - server2:9100
