+## Network Access
+
+When checking URL indicators, MVT follows recognized shortened URLs with an
+HTTP `HEAD` request. The following environment variables control these
+requests:
+
+- `MVT_NETWORK_ACCESS_ALLOWED` enables or disables network requests. It defaults
+  to `true`. Set it to `false` to prevent MVT from attempting to resolve
+  shortened URLs.
+- `MVT_NETWORK_TIMEOUT` sets the request timeout in seconds. It defaults to
+  `15`.
+
+For example, to run IOC checks without resolving shortened URLs:
+
+```bash
+MVT_NETWORK_ACCESS_ALLOWED=false mvt-ios check-iocs \
+    --iocs ~/iocs/malware.stix2 /path/to/iphone/output/

 ## STIX2 Support
