Rate limits reduce excessive use, but IP-only limits can affect many legitimate mobile users together.
Evaluation approach
Consider account, operation, registration and resource cost. Expensive endpoints need different budgets from simple reads.
Application example
Limit SMS attempts separately, without giving an account unlimited fresh allowance whenever its network changes.
Limits and considerations
Rate limits do not replace authorization or fraud analysis.
How mobile networks affect identity
Many users may share an exit address, while one user may change networks frequently. Treating an IP as a sole identity can produce both missed abuse and false blocks.
Checks and decisions
- Limit by cost
- Test shared IPs
- Manage retries
