You might see 185.63.253.2pp in logs, security reports, or DNS tools. It looks like an IP address, but the “pp” suffix breaks standard formatting. In this article I explain what 185.63.253.2pp is (and isn’t), why it shows up, what risks it carries, and how you should respond.
What Is 185.63.253.2pp?
On first glance, it seems like an IPv4 address. But valid IPv4 addresses have only numbers in each octet (0-255) separated by dots. The letters “pp” at the end make 185.63.253.2pp invalid as a standard IP. Many analyses suggest it’s based on a real IP (185.63.253.2) that has been altered or flagged using “pp.”
The “pp” might be:
-
A tagging or labeling suffix added for internal tracking
-
A way to obfuscate or disguise the real IP
-
A formatting error or glitch in logs or scripts
-
A custom protocol or annotation used in certain systems
Because of that suffix, network systems that strictly validate IPs will reject 185.63.253.2pp as invalid.
What We Know About 185.63.253.2 (Base IP)
To understand 185.63.253.2pp, we look at its base IP without the “pp.” Here’s what is known about 185.63.253.2:
-
It is geo-located in the Netherlands
-
The ISP or hosting provider is HostPalace Datacenters Ltd
-
The IP is not currently flagged on major malicious IP blacklists
So the clean IP (without the “pp”) seems legitimate and relatively safe, but the modified version with “pp” raises questions.
Why 185.63.253.2pp Appears in Logs or Reports
Here are reasons why you might see 185.63.253.2pp:
Tagging or Annotation
Some systems append short codes (like “pp”) to IPs as tags to classify traffic types, proxy levels, or internal notes.
Obfuscation or Bypass Technique
Attackers or automated scripts may use IP strings with extra characters to evade filtering rules or avoid blacklisting.
Logging / Parsing Errors
Mistakes in code or log parsing may merge fields incorrectly, causing the suffix to attach unintentionally.
Placeholder or Fake Data
During development or testing, engineers sometimes use fake or placeholder values (like adding “pp”) so they’re obviously not real IPs. If such data accidentally gets into production logs, you’ll see something like 185.63.253.2pp.
Risks & Concerns Around 185.63.253.2pp
Monitoring & Analysis Confusion
Because it’s not valid, logs that include 185.63.253.2pp may break analytics or be ignored by security tools. That may hide suspicious activity.
Potential Redirection / Phishing
If used in URLs or redirects (for example, http://185.63.253.2pp/), it might lead to malicious pages or attempts to trick users into thinking it’s a normal IP.
Misleading Attribution
Security or abuse reports might pick 185.63.253.2pp and link it (incorrectly) to the legitimate base IP, potentially flagging an otherwise clean entity.
Hidden Malicious Behavior
The odd format may be part of advanced attempts to evade detection, embed malware, or sneak in traffic via nonstandard entries.
How to Investigate 185.63.253.2pp Yourself
If you see 185.63.253.2pp in logs or tools, follow these steps:
-
Strip the “pp” and check the base IP (185.63.253.2) using IP lookup, WHOIS, and blacklist tools.
-
Search logs around it: look for similar entries (with or without “pp”), frequency, timing, and source.
-
Check scripts or systems that generate log entries—maybe a faulty parser or field concatenation causes the suffix.
-
Use firewall or IDS rules to flag any unusual access involving 185.63.253.2 or variations of it.
-
Monitor behavior: if there are failed logins, high request rates, unusual patterns, treat as suspicious.
Safer Practices & Precautions
-
Block or isolate entries with malformed IPs like 185.63.253.2pp until you verify them
-
Keep your logging and parsing systems strict: they should reject invalid IP formats
-
Use advanced security tools that don’t rely solely on pattern matching
-
Regularly audit your logs and remove dummy or test data before going live
Conclusion
185.63.253.2pp is not a valid IPv4 address—it combines a real IP (185.63.253.2) with a nonstandard suffix. That suffix likely serves for tagging, obfuscation, or error rather than a functional address. The base IP belongs to a hosting provider in the Netherlands and shows no red flags currently. But whenever you see 185.63.253.2pp in systems or logs, treat it with suspicion: it can disrupt analytics, hide activity, or signal coding mistakes or malicious intent. Always investigate the base IP, check log context, and enforce strict parsing rules.
