In our digitally connected world, every device that connects to the internet has one thing in common — it uses an IP address. Just like a home needs a mailing address, your phone, laptop, or server needs an IP to send and receive data. One such IP address might be 185.63.263.20 — but what does that mean? Where is it from? Can we trace it? Is it dangerous? Let’s break down everything you need to know.
What is an IP Address?
IP stands for Internet Protocol, which is a set of rules governing how devices communicate over a network. An IP address is a unique string of numbers that identifies a device on the internet or a local network. There are two main types of IP addresses:
- IPv4: This is the older format, consisting of four sets of numbers separated by dots (e.g., 185.63.263.20).
- IPv6: A newer format, created because we’re running out of IPv4 addresses. These look like:
2001:0db8:85a3:0000:0000:8a2e:0370:7334.
So when we talk about 185.63.263.20, we’re referring to an IPv4 address.
Is 185.63.263.20 a Valid IP Address?
Let’s pause here. You might be thinking: “Wait, is that even a real IP?” Good catch. In fact, 185.63.263.20 is NOT a valid IP address.
Why?
The valid range for each of the four parts of an IPv4 address (called octets) is 0 to 255. The number 263 is outside that range.
So technically, 185.63.263.20 could not be assigned to any device. It’s an invalid IP address.
But don’t worry — this gives us a great learning opportunity. Let’s explore how to analyze IPs properly, how to validate them, and how to trace real ones using safe and effective tools.
How to Check if an IP Address is Valid
Step 1: Understand the Format
IPv4 addresses look like this: XXX.XXX.XXX.XXX. Each “XXX” is a number from 0 to 255. So:
- Valid:
192.168.1.1 - Invalid:
185.63.263.20(because 263 > 255)
Step 2: Use Online IP Validators
Here are some tools to help:

- https://ip-api.com/
Paste any IP (like8.8.8.8– Google’s DNS) and get location, ISP, blacklist status, and more.
How IP Addresses Work Behind the Scenes
Let’s say you’re at a coffee shop, browsing websites. Your phone sends a request to a server that hosts your favorite site. That server sends back data.
But how does it know where to send it?
Thanks to your public IP address, your request includes a return address. That way, the server can reply directly to your device.
There are two main kinds of IP addresses:
| Type | Description | Example |
|---|---|---|
| Public IP | The address visible to the internet | 8.8.8.8 |
| Private IP | Used inside your home or office network | 192.168.0.1 |
How to Trace an IP Like 185.63.263.20 (If It Were Valid)
Let’s imagine 185.63.263.20 was a real, working IP. Maybe you saw it in your logs or firewall report. Here’s what you’d do.
Step 1: Use whois Lookup
This tells you who owns the IP — maybe a company, ISP, or hosting provider.
Sites like:
- https://whois.domaintools.com/
- https://www.arin.net/
Paste the IP, and you’ll see something like:
OrgName: XYZ Hosting Services
Country: Germany
Abuse Contact: abuse@xyzhost.com
Step 2: Perform a Geolocation Lookup
Use:
- https://iplocation.net/
- https://tools.keycdn.com/geo
Find out: - Country
- City
- ISP
- Time zone
Anecdote: One time, a client of mine noticed strange traffic from an IP in his server logs. He traced it to a server farm in Ukraine — it turned out to be a bot scraping his product listings.
Step 3: Run a Ping or Traceroute
This checks if the IP is reachable and how many “hops” it takes to get there.
Use Command Prompt:
ping 8.8.8.8
tracert 8.8.8.8
Or on Mac/Linux:
ping 8.8.8.8
traceroute 8.8.8.8
What If an IP Like 185.63.263.20 Tries to Access My System?
Even if 185.63.263.20 isn’t valid, the advice here helps for any suspicious IP.
Step 1: Block it on Your Firewall
If you’re using:
- Windows Defender Firewall
- UFW on Linux
- IPTables
You can add rules to block the IP.
Step 2: Check for Malware or Intrusions
If you see odd traffic from an unknown IP, it might be:
- A bot or crawler
- A hacker scanning for weaknesses
- A misconfigured server
Run: - Antivirus scan
- Port scanner check
- Network monitoring tool like Wireshark
Why Understanding IPs Matters (Even If They’re Fake)
Sure, 185.63.263.20 isn’t valid. But learning to read IPs, track them, and block them is crucial for:
- System administrators
- Cybersecurity analysts
- Small business owners with websites
- Everyday users who value privacy
Quick Tip: Use a VPN to mask your own IP when browsing — this protects your identity and location from prying eyes.
Glossary of Important IP Terms
| Term | Meaning |
|---|---|
| IPv4 | The older IP format with 4 numbers (e.g., 192.0.2.1) |
| IPv6 | Newer format designed to replace IPv4 |
| Public IP | Your device’s address visible to the outside world |
| Private IP | Internal address used in home/office networks |
| WHOIS | A tool that shows who owns an IP or domain |
| Blacklist | A list of known bad IPs (spammers, attackers, etc.) |
What To Do When You Encounter a Suspicious IP
Let’s say you found a weird IP like 185.63.263.20 trying to connect to your server.
Follow this checklist:
- Validate the IP
- Check ownership via WHOIS
- Look up location
- Check if it’s blacklisted
- Block it on your firewall
- Monitor your logs
- Report abuse if necessary
Real-World Story: How a Fake IP Saved My Client’s Website
I once worked with a small eCommerce store. They had a sudden spike in traffic, and their server crashed. When we checked the logs, we saw repeated hits from a strange-looking IP: 300.45.90.78 (also invalid, like 185.63.263.20).
That’s when we realized: the traffic wasn’t real. It was a DDoS attack using spoofed IPs. By blocking large IP ranges, we stabilized the server and added Cloudflare for protection.
Moral of the story: Even fake IPs can signal real threats.
Key Takeaways
- 185.63.263.20 is an invalid IPv4 address — but a great learning example.
- You can validate, trace, and block IPs using free tools and built-in commands.
- Suspicious IPs should always be treated seriously — even if they’re just typos or fakes.
- Learning how IP addresses work empowers you to protect your devices, networks, and privacy.
Frequently Asked Questions
What is the highest number in an IPv4 address?
255 — anything higher (like the 263 in 185.63.263.20) is invalid.
Can I find someone’s exact address from an IP?
Not usually. You might get city or region info, but exact addresses require legal access (e.g., by law enforcement).
Is it illegal to trace IP addresses?
No. Looking up publicly available IP info is legal. Just don’t attempt to hack or harass the owner.
Final Thoughts
Understanding IP addresses doesn’t have to be complicated. Whether it’s a valid IP or a learning example like 185.63.263.20, knowing how to validate, trace, and block addresses is a key skill in today’s digital world.
So next time you spot a strange IP in your server logs or firewall alerts, don’t panic. Just follow the steps, use your tools, and protect your space online.
