The digital world is full of unusual codes, strange log entries, and mysterious IP formats that often leave users confused. One such unfamiliar entry is 185.63.253.2pp. At first glance, it looks like a normal IP address, but the extra “pp” makes it unusual and raises questions about where it comes from and why it appears in logs.
This guide breaks down every possible explanation, explores the cybersecurity risks, and shows you how to investigate and respond effectively if you encounter this identifier.
What Is 185.63.253.2pp?
Normally, an IP address like 185.63.253.2 follows the standard IPv4 format (four groups of numbers separated by dots). But when “pp” is attached, it breaks the usual format. Since it doesn’t follow official Internet Protocol standards, experts believe it is a custom label or altered notation.
Here are the most common interpretations of “pp”:
Typographical Error
- Sometimes “pp” is simply a mistake. An administrator or system might have added extra characters accidentally.
- Example: During a bulk log export, a “pp” could appear if the parser added a tag incorrectly.
Proxy/Port Reference
- “pp” might stand for Proxy Port or Peer-to-Peer.
- Example: In proxy servers, admins occasionally append tags to identify special routing.
Custom Tracking Tag
- Certain analytics or internal systems append letters to track unusual requests.
- Example: A research lab logging malicious IPs may add “pp” to mark “potentially problematic.”
Malicious Obfuscation
- Attackers sometimes modify IP notations to confuse automated scanners or filters.
- Example: A botnet might insert “pp” so that it bypasses naïve detection scripts that expect standard IP formats.
Is 185.63.253.2pp a Real IP Address or Just a Modified Identifier?
From a technical standpoint, 185.63.253.2pp is not a valid IP address under IPv4 or IPv6 standards. IP addresses are strictly numeric (or hexadecimal in IPv6) and do not allow alphabetical characters like “pp.”
What users actually see in logs is usually a modified representation of a real IP address, not an address that can function on the internet by itself. The base IP (185.63.253.2) may still be legitimate, but the added suffix changes how systems interpret it.
This distinction is important because:
- Firewalls may fail to parse the entry correctly
- Analytics tools may record it as an unknown source
- Security scanners may flag it as malformed data
Understanding that 185.63.253.2pp is an identifier string, not a routable IP, helps prevent confusion and unnecessary panic during investigations.
Why Is 185.63.253.2pp Suspicious?
185.63.253.2pp looks odd from the start. The core IP, 185.63.253.2, is real. But the extra “pp” makes no sense in standard formats. That unusual tag is why many call it suspicious.
Strange notations often point to spam or bot activity. They sometimes appear in analytics as fake traffic. This tricks site owners and makes reports unreliable.
Security checks show IPs in this range linked to shady tasks. These include spamming, malware, and even brute-force login attempts. Because of this, most experts treat 185.63.253.2pp as a red flag.
Technical Breakdown: IP Address Hosting and Origin
A deeper look into 185.63.253.2 reveals that it is registered to HOSTPALACE DATACENTERS LTD, a company located in Lelystad, Flevoland, Netherlands. This IP range (185.63.253.0/24) is typically used by data centers, VPN providers, and hosting services.
This means the address is part of a larger infrastructure that powers private browsing, server hosting, or possibly remote desktop connections. It is commonly associated with platforms that value anonymity and secure access.
Why Does 185.63.253.2pp Appear in Logs?

People have reported seeing this unusual entry in multiple contexts. Here are the most common scenarios:
- Firewall Logs

Can 185.63.253.2pp Affect Website Performance or Data Accuracy?
While 185.63.253.2pp does not directly damage servers, it can indirectly impact performance and reporting accuracy if left unchecked. Repeated requests from modified or proxy-based IP formats can increase server load, especially when generated by bots or automated scripts.
In analytics platforms, such entries often:
- Inflate traffic numbers artificially
- Skew bounce rate and session duration metrics
- Hide genuine user behavior under spam traffic
Over time, this can lead to poor decision-making, as site owners rely on inaccurate data. From a performance perspective, excessive bot requests may consume bandwidth, slow response times, and trigger unnecessary security alerts.
Filtering malformed IP patterns early helps maintain both system efficiency and clean analytics data.
Common Use Cases
Here are some likely applications where 185.63.253.2pp might appear:

How Attackers Use Modified IP Formats Like 185.63.253.2pp
Cybercriminals often alter standard IP formats to avoid detection. Modified tags like “pp” can help attackers:
- Slip past simple IP-based firewalls
- Disrupt analytics accuracy
- Evade automated scanners
- Hide patterns in botnet traffic
Security tools expecting clean IPv4 formats may fail to parse the entry correctly, allowing attackers to bypass weak filtering systems.
How to Differentiate Legitimate Tags from Malicious IP Manipulation
Not every altered IP is harmful. Some legitimate systems use custom labels for internal management. To separate harmless cases from dangerous ones, consider:
Frequency:
One-time appearance = likely harmless
Repeated appearances = investigate further
Context:
Appears during server attacks? Probably malicious.
Appears in internal logs? Could be system-generated.
Reputation:
Use tools like AbuseIPDB, VirusTotal, or Talos to check if the base IP is linked to spam or attacks.
This step helps avoid false alarms and ensures you only block harmful traffic.
