Hello! If the nodes are restarted, will the IP 172.31.61.121 be retained?

Until unless your not stopping or restarting Master Node/Worker Node EC2 instance IP address is not going to change. If you you stop instance then IP will be changed, if you want static IP address then use elastic IP.

[ANSAR SHAIK](https://hashnode.com/@ansarshaik965) Thanks! So for preproduction/production grade clusters, the best practice is to use static Ip?
