The added “p4” at the end is not part of the standard IP format. That’s an important detail.
What this usually means
From experience and from analyzing similar cases, strings like 111.90.150.2p4 are typically:
- A log label or internal identifier
- A proxy or routing marker added by software

Most people encounter 111.90.150.2p4 in one of these situations:
1. Website or Server Logs

Is 111.90.150.2p4 Dangerous?
This is the big question — and the honest answer is:
👉 The address itself is not automatically dangerous.
An IP (or IP-like string) is not good or bad on its own. What matters is behavior.

Things that may require attention:
- Repeated failed login attempts
- Excessive requests in a short time
- Access to restricted endpoints
- Triggered firewall rules
- Matching known malicious behavior patterns
If 111.90.150.2p4 appears alongside suspicious behavior, then it’s worth investigating further.
How I Personally Check an IP Like This
When I see something unfamiliar, I don’t jump to conclusions. I follow a simple process:
Step 1: Strip the Extra Characters
I focus on the base IP:
- 111.90.150.2
That’s the actual address.
Step 2: Check the Activity
I look at:
- Request frequency
- URLs accessed
- Time patterns
- User-agent strings
Most “scary-looking” IPs turn out to be harmless bots or crawlers.
Step 3: Use Reputable IP Lookup Tools
I check:
- General geolocation (country, ISP)
- ASN information
- Whether it appears on known abuse lists
Step 4: Decide Based on Behavior, Not Fear
If it’s harmless, I do nothing.
If it’s suspicious, I:
- Rate-limit
- Block temporarily
- Monitor further
