Let’s get started.
What Is an IP Address?
An IP address Internet Protocol address is a number that identifies each device connected to the internet. It’s like a digital address that helps data find its way to the right place.
There are two types of IP addresses:
IPv4: Most common, made up of four sets of numbers e.g., 192.168.0.1
IPv6: Newer, longer format with letters and numbers
IPv4 Format:
An IPv4 address looks like this: XXX.XXX.XXX.XXX, where each “XXX” is a number from 0 to 255.
Example of valid IPs:
8.8.8.8
192.168.1.1
185.63.100.20
Example of invalid IP:
185.63.263.20 → 263 is not in the allowed range 0-255
Why Is 185.63.263.20 Invalid?
Although 185.63.263.20 looks like a regular IP address, it has a technical problem. The third number 263 is too high.
IP Structure Check Table:
| Octet Position | Value | Valid Range | Status |
|---|---|---|---|
| First | 185 | 0–255 | Valid |
| Second | 63 | 0–255 | Valid |
| Third | 263 | 0–255 | Invalid |
| Fourth | 20 | 0–255 | Valid |
Because of this, 185.63.263.20 is not a real or working IP address.
Where Might You See 185.63.263.20?
Even though it’s not a valid IP, it may still appear in different systems or logs.
You might see this IP in:
Server log files
Email headers
Firewall alerts
Network monitoring tools
Intrusion detection system IDS reports
This could be a sign of:
Brute-force attack
Port scanning
Spam or phishing email
Botnet communication
Why Would Someone Use a Fake IP Address?
Cybercriminals may use invalid or fake IPs to hide their true identity or confuse defenders.
Common Reasons:
Evade detection by firewalls or intrusion systems
Spoof locations to look like traffic from trusted sources
Cause log errors to break monitoring tools
Mask malicious activity in large-scale attacks
Is 185.63.263.20 a Threat?
While it is not a valid IP address, its appearance in logs may indicate malicious behavior. It might be used as a spoofed IP address in phishing emails or cyberattacks.
Possible Risks:
| Behavior | Description |
|---|---|
| Spoofing | Faking an IP to look like someone else |
| Phishing | Trick emails with fake headers/IPs |
| Logging Bug | Faulty software writing bad IPs to logs |
| Evasion Technique | Hiding real source of traffic or payload |
What Should You Do If You See 185.63.263.20?

Use Intrusion Detection Systems IDS
Monitor traffic logs regularly
Block suspicious IPs promptly
Train your team on spotting phishing and spoofing
Keep software and firmware updated
These simple steps can help prevent most common attacks involving fake or spoofed IP addresses.
Common Tools to Investigate IPs
Tool Name | Use Case | Website |
|---|---|---|
| AbuseIPDB | Check if IP is blacklisted | abuseipdb.com |
| VirusTotal | Scan IP, file, or URL for threats | virustotal.com |
| DomainTools | WHOIS and IP lookup | whois.domaintools.com |
| MXToolbox | Email header/IP analysis | mxtoolbox.com |
How Fake IPs Can Disrupt Your Systems
Even though fake IPs like 185.63.263.20 are not real, they can still cause issues:
Break automated scripts
Confuse reporting dashboards
Waste analyst time during incident response
Trigger false positives in security tools
That’s why identifying and filtering them is important.
