The IP address 185.63.253.300 has drawn attention from cybersecurity analysts, web admins, and curious users due to its unusual activity or presence in server logs. Whether you’ve encountered this IP in your website analytics, firewall logs, or through a threat detection tool, understanding the nature of this IP address is crucial. In this in-depth article, we will explore everything from WHOIS data to geographic location, reverse DNS records, ISP ownership, and even potential threat intelligence around this IP. If you’re looking to trace, analyze, or block 185.63.253.300, this comprehensive guide will give you all the insights you need.
🌐 IP Lookup and Geolocation of 185.63.253.300
Upon performing an IP lookup for 185.63.253.300, it is essential to first realize that 300 is not a valid octet in the IPv4 range. IP addresses consist of four sets of numbers (octets), each ranging from 0 to 255. Since 185.63.253.300 exceeds this range, it technically does not represent a valid IP address under the IPv4 protocol, which immediately raises questions about its origin and usage.
However, many logs or tracking tools may still report malformed or spoofed IPs like this, especially in scenarios involving botnets, scanner bots, or intentionally deceptive sources. In such cases, the real IP could be obfuscated, and further analysis using server headers or traffic logs is required to trace the true source.
🕵️ WHOIS & ISP Data: Who Owns 185.63.253.300?
Typically, WHOIS data provides ownership and registration details of an IP. Since 185.63.253.300 is invalid, a direct WHOIS search may not yield results. However, you can inspect the broader range — for instance, 185.63.253.0/24 — which is a valid subnet. Looking into that range shows it belongs to:
-
ISP/Organization: M247 Europe SRL
-
Country: Romania (RO)
-
Abuse Contact: abuse@m247.ro
M247 is a hosting and data center company known for offering VPS and dedicated hosting. Unfortunately, IPs from large providers like M247 are sometimes misused for shady operations including mass scraping, DDoS activity, or spam campaigns. If 185.63.253.300 or a similar IP appears frequently in your server logs, it’s advisable to contact the ISP’s abuse team.
🛡️ Is 185.63.253.300 Malicious? Security & Threat Analysis
Since 185.63.253.300 is not valid under IPv4, one of two things may be happening:
-
The IP is spoofed, used in an attempt to bypass firewalls or confuse tracing tools.
-
It is a logging or parsing error where the IP was incorrectly logged or output by a script.
In cybersecurity, spoofed IPs are often used during DDoS attacks, email phishing headers, or bot scanning tools. If your analytics, web firewall, or server application is showing repeated attempts from this or similar IPs, it is recommended to perform the following:
-
Enable deep packet inspection (DPI).
-
Use a WAF (Web Application Firewall) to block malformed requests.
-
Monitor other IPs in the 185.63.253.x range.
Tools like VirusTotal, AbuseIPDB, or AlienVault OTX can help assess whether nearby IPs from this block have a bad reputation.
🔒 How to Block or Report 185.63.253.300
To maintain your server or application security, it’s critical to know how to deal with suspicious IP addresses. Even though 185.63.253.300 is malformed, related subnets can be filtered using:
1. Firewall Rules (Linux iptables example):
2. Apache/.htaccess Block:
3. Nginx Deny Rule:
4. Reporting Abuse:
You can email abuse@m247.ro with full logs, timestamps, and request headers to help them investigate abuse on their network.
📍 Reverse DNS & Hosting Analysis
Reverse DNS (rDNS) lookup can provide further context by showing the domain name associated with an IP. Since 185.63.253.300 is not valid, it doesn’t resolve to any domain. But nearby IPs in 185.63.253.0/24 may resolve to various VPS or hosting clients of M247. This highlights the importance of examining the full subnet or using honeypot traps to catch bot behavior.
✅ Conclusion
The IP 185.63.253.300 may look legitimate at first glance, but upon closer inspection, it is clear that it is technically invalid in IPv4 format. This raises red flags, especially for server administrators and cybersecurity experts. Whether it’s being spoofed in an attack, incorrectly logged, or part of a suspicious traffic pattern, treating it as a potential security concern is justified. By analyzing the surrounding subnet, checking hosting records, applying firewall rules, and reporting abuse, you can protect your infrastructure from any real or perceived threats connected to this malformed IP address.
