## Intelligence Narrative

IP 121.52.157.140 presents a moderate risk profile with conflicting geolocation indicators. The IP resolves to a Pakistani government domain (qet-hec.gov.pk), suggesting legitimate government infrastructure operations. However, multiple technical indicators point to Chinese origin, including TLS certificate issuance location and geolocation data.

The subnet demonstrates clean abuse density with no malicious activity observed. One neighboring IP (121.52.157.109) shows elevated risk scoring (50) but remains within acceptable parameters for network infrastructure.

Primary Concern: Geolocation mismatch between claimed Pakistani government ownership and technical indicators pointing to Chinese infrastructure. This discrepancy warrants verification against official Pakistani government network registries.

Recommended Monitoring: Continue surveillance but no immediate blocking action recommended. The government domain association suggests legitimate operational use.
