## Executive Summary
IP address 47.82.53.21 was classified as Low Risk with a risk score of 25. The address is associated with Alibaba Cloud LLC (ASN 45102) and operates as a cloud computing infrastructure endpoint. No active threat indicators were observed during analysis.
## Network & Infrastructure Profile
The IP address resides within the AL-3 network block (47.74.0.0/15) operated by Alibaba Cloud LLC. Geographic analysis returned United States as the consensus country, though probe data indicated a claimed latitude/longitude of 1.3667, 103.8 with a distance of 10,372.4km from the claimed location. The infrastructure is classified as CloudCompute with hosting capabilities enabled.
Network role assessment confirmed the address is cloud-based and hosting-enabled. No open ports were detected, and service discovery returned "Firewalled / No Services." DNS analysis showed no forward resolution and no PTR hostnames. Email authentication records (SPF/DMARC) were absent.
## Threat Assessment
Threat indicators remained absent across all queried sources. The IP was not flagged as a Tor exit node, known attacker, or spam source. Blacklist enumeration returned zero entries. No known campaigns were correlated with this address. DNSBL analysis indicated one listing across eight total lists, though this does not appear to impact the overall low-risk classification.
Control plane analysis showed the address originates from BGP prefix 47.82.48.0/21. Route stability was marked as false with zero route changes in the previous 30 days. RPKI and IRR consistency data were unavailable. DNSSEC validation returned true.
## Neighborhood Analysis (47.82.53.0/24)
The /24 subnet was classified as clean with an abuse density of 0. Three total sibling addresses exist within the block. Risk distribution across the neighborhood showed zero high-risk and zero medium-risk addresses. Two neighbors were identified: 47.82.53.58 (risk score 0, authority score 50) and 47.82.53.206 (risk score 25, authority score 50). No threat-sibling addresses were present in the subnet.
## Historical Signals
Sixteen observations were recorded in the observation history. Recent signals from 2026-07-28 included traceroute data showing 21 hops, geolocation probes with 5 probes and average RTT of 257.2ms, infrastructure classification, network ownership, and subnet analysis. Ownership changes totaled zero, and threat persistence days were recorded as zero. The IP was not classified as persistently malicious.
## Recommended Actions
No specific security actions or firewall rules were generated by the risk assessment. The low-risk classification (score 25) with no active threat indicators suggests standard cloud infrastructure monitoring is appropriate. The absence of actionable recommendations aligns with the overall benign profile.
