Before performing external network testing, what should you do with your Internet Service Provider?

• A. Inform them
• B. Ignore them
• C. Upgrade service plan
• D. Change providers

Answer: (A)

Before performing external testing, inform your Internet Service Provider about the planned activity. External scanning and traffic spikes can look like abuse to the ISP’s monitoring systems, and many providers have terms of service that could block, throttle, or suspend your connection if they’re not aware of legitimate testing. By giving them a heads-up, you can get guidance or approval, set up an acceptable testing window or rate limits, and ensure the activity won’t disrupt service or violate policy. Provide details such as scope, targets, timing, and contact information so the ISP can distinguish your authorized test from malicious activity.

Ignoring them risks automatic abuse notifications or disconnection, while upgrading the plan or changing providers doesn’t address the need for authorization and can complicate the testing workflow.
