The address demonstrates benign CDN infrastructure characteristics with no observed malicious activity, threat indicators, or blacklist associations. Recommended treatment: Monitor as infrastructure; no blocking required. \--- \### OWNERSHIP & NETWORK CLASSIFICATION | Attribute | Value | |-----------|-------| | **Organization** | Akamai Technologies, Inc. | | **ASN** | 20940 | | **Network Block** | 23.192.0.0/11 | | **Country** | United States (Massachusetts, Boston) | | **Infrastructure Type** | CDN (Content Delivery Network) | | **Provider Score** | 0 | | **Authority Score** | 0 | The IP resolves to hostname \`a23-221-236-100.deploy.static.akamaitechnologies.com\` with forward DNS confirmation. \--- \### RISK ASSESSMENT | Metric | Value | Assessment | |--------|-------|------------| | **Risk Score** | 20 | Low Risk | | **Abuse Confidence** | N/A | Not Applicable | | **Blacklist Count** | 0 | Clean | | **Threat Indicators** | None | No Malicious Signals | | **Known Campaigns** | None | No Correlation | | **Tor Exit/Proxy** | No | Legitimate CDN | The IP exhibits no evidence of malicious use, spam distribution, or attack campaign participation. \--- \### SERVICE & NETWORK ROLE ANALYSIS | Service Characteristic | Status | |------------------------|--------| | **Open Ports** | None detected | | **TLS Certificate** | N/A | | **HTTP Services** | None exposed | | **Network Classification** | CDN / Firewalled | | **Cloud Infrastructure** | Yes | The address shows no active services, indicating it is part of Akamai's upstream CDN infrastructure rather than an endpoint-facing service. \--- \### GEOLOCATION VALIDATION | Parameter | Value | |-----------|-------| | **Claimed Location** | Boston, Massachusetts, US | | **Coordinates** | 39.83°N, -98.58°W (inferred) | | **Reported Distance** | 5,663 km | | **Observed RTT** | 15.8 ms (avg) | | **Validation Status** | ⚠️ GEOLOCATION INCONSISTENCY | **Note:** Geovalidation indicates RTT (12-20ms) is inconsistent with claimed Boston location, which would require minimum 113ms. This discrepancy is common with CDN anycast networks and does not indicate malicious activity. \--- \### OBSERVATION HISTORY (18 Signals) **Timeframe:** 2026-07-14 to 2026-07-27 \- **Consistent Classification:** All observations confirm CDN/Akamai infrastructure \- **Threat Persistence:** 0 days observed \- **Malicious Activity:** None detected \- **Control Plane Signals:** Basic operator score (0.2609), route stable, DNSSEC valid \- **Geo Signals:** Minor inconsistencies noted but within CDN operational patterns \--- \### NETWORK RELATIONSHIPS \- **DNS Associations:** 3 entries pointing to \`a23-221-236-100.deploy.static.akamaitechnologies.com\` \- **Network Associations:** 4 entries linked to AKAMAI network \- **Related Entities:** No malicious or suspicious correlations identified \- **Certificate Matches:** 0 \--- \### NEIGHBORHOOD ANALYSIS (Subnet: 23.221.236.0/24) | Metric | Value | |--------|-------| | **Abuse Density** | 0.00 (Clean Subnet) | | **Total Siblings** | 2 | | **Active Siblings** | 0 | | **Threat Siblings** | 0 | | **Neighbor IP** | 23.221.236.168 (Risk: 20, Authority: 60) | The /24 subnet demonstrates clean abuse characteristics with no high or medium risk neighbors. \--- \### RECOMMENDED ACTIONS **Immediate Actions:** None Required **Firewall Rules:** Not required for this IP **SOC Handling:** \- Treat as benign CDN infrastructure \- No blocking or rate-limiting recommended \- Standard CDN traffic monitoring applies \- Investigate only if unusual traffic patterns detected **Monitoring Triggers:** \- If traffic volume exceeds expected CDN thresholds \- If non-standard ports begin appearing \- If geovalidation patterns shift significantly \--- \### INTELLIGENCE CONCLUSION IP 23.221.236.100 represents legitimate Akamai CDN infrastructure with no observable security threats. The IP should be classified as low-risk network infrastructure. Standard CDN egress/ingress policies apply. No defensive measures beyond routine network monitoring are warranted. **Confidence Level:** HIGH (based on 18 observations, clean threat profile, and established CDN infrastructure patterns) \--- *Report generated by IPDebrief Intelligence Operations* ## Nearby addresses - 23.221.236.4 (https://ipdebrief.com/23.221.236.4) - 23.221.236.5 (https://ipdebrief.com/23.221.236.5) - 23.221.236.6 (https://ipdebrief.com/23.221.236.6) - 23.221.236.7 (https://ipdebrief.com/23.221.236.7) - 23.221.236.8 (https://ipdebrief.com/23.221.236.8) - 23.221.236.9 (https://ipdebrief.com/23.221.236.9) - 23.221.236.10 (https://ipdebrief.com/23.221.236.10) - 23.221.236.11 (https://ipdebrief.com/23.221.236.11) - 23.221.236.12 (https://ipdebrief.com/23.221.236.12) - 23.221.236.13 (https://ipdebrief.com/23.221.236.13) - 23.221.236.14 (https://ipdebrief.com/23.221.236.14) - 23.221.236.15 (https://ipdebrief.com/23.221.236.15) --- Source: IPDebrief, "23.221.236.100 IP intelligence", https://ipdebrief.com/23.221.236.100, updated 2026-10-30.
