IP blocking (or whitelisting) is useless when your target lives in the cloud. Many CDNs have a massive pool of IPs which change rapidly. Autoscaling systems have TTLs as low as 60 seconds. Not only will you fail to block (or allow) requests, but you will also block (or allow) requests to completely different organizations on the same multi-tenant cloud environment.
