• Filter on running instances (you can drop that part if you don't need it)
• Query for each PublicIPaddress and the Name Tag, handling when Name isn't set

  --filter "Name=instance-state-name,Values=running" \
  --query "Reservations[*].Instances[*].[PublicIpAddress, Tags[?Key=='Name'].Value|[0]]" \
  --output text
