A summary table of useful tools

Checklist when checking website IP

• ✔ Lookup IP of main domain and subdomain
• ✔ Identify hosting server location
• ✔ Check if using CDN (cloudflare…)
• ✔ Cross-check IP from different sources
• ✔ Record results and periodic check times

Note when checking IP – it's not always “accurate”

Content filtering services, CDNs like Cloudflare can hide the real IP of the origin server. This makes identifying the IP address difficult in many cases.

Takeaway

Checking a website's IP is not too difficult, but you need to choose the right tool for each purpose. Regular checks help businesses easily detect network issues or changes from the hosting provider.

Detailed guide on how to check IP from URL accurately and quickly

1. Basic steps to check IP from URL

Below is a checklist to help you perform the lookup in just a few minutes:

• ✅ Access a reputable IP lookup tool (such as WhatIsMyIPAddress, DNSChecker, Hostinger…)
• ✅ Enter the website URL you want to check (e.g.: example.com)
• ✅ Click “Check” or “Find” for the tool to process
• ✅ View results showing IPv4 IP, IPv6, host name…

2. Use Command Prompt (Windows) or Terminal (macOS/Linux)

Another accurate way that doesn’t require a browser is to use the command:

• ping example.com ➝ Instantly returns the IP result
• nslookup example.com ➝ displays the DNS server and IP address

Example: When running ping facebook.com, the system will return the IP as 157.240.229.35. Actual data from Cloudflare’s 2023 report recorded that 83% of website slowdowns are due to DNS or incorrect IP.

4. Some important notes and potential risks

• ⚠️ Some websites using CDN like Cloudflare will not display the real IP
• ⚠️ IP may change if the website uses shared hosting
• ⚠️ IP lookup does not help determine the exact server location unless you have access to the actual host

Analyze IP information to enhance security and optimize Website

Why should you monitor website IP?

Analyzing IP addresses helps businesses identify suspicious traffic sources, thereby limiting DDoS attacks or unauthorized access. An IP address that continuously sends requests to the server may be a sign of a bot or malicious script.

Organizations like Cloudflare (2023 Report) recommend that websites regularly check IPs to:

– Detect brute force and spam activities early.
– Block IPs from unwanted regions.
– Monitor the performance of the origin server via the server IP being pointed to.

Factors to analyze when checking IP

A website's IP address not only shows the server location, but is also directly related to stability and SEO. Below are the factors you should check when looking up an IP:

– Geographical location of the IP (affects page load speed for users)
– Hosting provider
– Blacklist status (Is the IP listed as malicious?)
– Uptime rate based on access history (check with tools like Uptime Robot)

Real-life example: An e-commerce website in Vietnam with an IP located in Europe recorded a page load time 2.7s slower for local users (source: GTMetrix 2023 update).

Checklist: Actions to take immediately

• Look up the real IP of the website using WHOIS or DNS Lookup tools
• Compare with the IP displayed in the browser ⇒ detect proxy or CDN
• Check if the IP is listed in the spamhaus.org blacklist
• Analyze access logs to filter IPs that repeat abnormally over 200 times/day
• Note down backup server IPs and keep an internal network diagram (if any)

Challenges and important notes

Although it offers outstanding benefits, IP analysis is not simple if the website uses multiple layers of proxy or CDN like Cloudflare. These cases require analyzing the original header (X-Forwarded-For) and accessing server logs.

Furthermore, dynamic IPs or shared IPs can be affected by other websites on the same server if a shared IP is blacklisted.

Takeaway

An IP address may seem technical, but it plays a central role in both security and speed optimization. Don't overlook it in the process of running a professional website.

How to use IP data in competitor research and market expansion

Analysis of competitor's technical infrastructure

When checking a website's IP, you can identify the hosting provider, CDN technology, or security structure your competitor is using. This helps measure the level of investment and professionalism in their system.

• Identify server IP to know if the competitor uses VPS, shared or dedicated server
• Check DNS records to understand the structure of email, web app, and subdomain
• Use tools like BuiltWith or SecurityTrails to deeply analyze the technology stack

Identify target customer reach areas

IP data also shows where the website is serving many visitors from (via ISP or geo-IP). If you identify a market with high traffic, you can develop promotional campaigns in similar areas.

Action checklist for competitor research

• ✓ Perform IP queries using online IP check tools (such as IPinfo, ViewDNS)
• ✓ Note down CDN network, web server, and security system
• ✓ Track sites using the same IP via Reverse IP Lookup
• ✓ Compare server location with international marketing campaigns

Challenges when using IP data

IP data can be easily spoofed due to services like Cloudflare masking the real IP, or dynamic IPs making it impossible to accurately identify the actual server. Incorrect analysis may lead to misdirected targeting or wasted marketing resources.

Real example

A startup in Ho Chi Minh City discovered their main competitor hosted their server in Frankfurt, serving a large amount of traffic from Germany. Thanks to IP analysis data, their content team tried a German SEO campaign and attracted an additional 12,000 visits/month after 3 months (Source: DPS.MEDIA internal report 2023).

Takeaway

Looking up and analyzing website IPs not only helps you understand your competitors but also opens up strategic pathways for choosing the right market to expand into.

Important notes when choosing an IP lookup tool suitable for SMEs

Set criteria appropriate to business scale

Not every IP lookup tool is suitable for all types of businesses. SMEs should focus on practical criteria:

– Simple interface, easy to use for non-experts.
– Centralized lookup capability: check IPs of multiple domains at once.
– No high costs or cumbersome registration required.

Compare features and reliability

To optimize performance, you need to evaluate tools based on technical criteria:

– Accuracy of IP address and hosting (IP hosting error margin can vary by ±51%).
– Real-time data updates, avoiding hidden cache data.
– API support for automated system integration (especially important for SMEs developing websites). Example: A furniture company in Binh Duong once used a free tool, although the lookup speed was fast, it returned incorrect geographic locations by about 30%, leading to their location-based marketing campaign targeting the wrong customer segment.

Checklist for choosing an IP lookup tool

• ✅ Supports multi-check for multiple IPs or URLs
• ✅ Response time under 1.5 seconds per lookup URL
• ✅ Can distinguish between IPv4 and IPv6
• ✅ Does not store unnecessary user data
• ✅ Supports reporting or CSV export if analysis is needed

Common warnings & challenges

– Some tools use outdated IP data → easily leading to errors in geographic location or service provider.
– For SMEs with domains using Cloudflare or CDN networks, the real IP may be “masked”, requiring specialized tools to identify the original IP.

Takeaway

Choosing the right IP lookup tool for SMEs helps businesses optimize data retrieval, ensure accuracy when implementing IP-based outreach campaigns, and minimize errors in user geolocation. Don't overlook checking for updates and extensibility features when comparing options.

Integrate IP checking into the operation and professional Website development process

Why is IP checking necessary in the operation process?

Identifying the website's IP address not only serves security purposes but also supports more efficient system administration. Especially in a Cloud environment or when using a Proxy, the IP helps clearly determine the routing point of traffic.

• Analyze abnormal traffic to filter bots or unwanted sources.
• Server identification active when there are multiple staging/test environments.
• Support the technical team in monitoring uptime and responding quickly to incidents.

IP check should be built as a step in DevOps

Integrating IP lookup into the CI/CD process brings outstanding benefits for testing and deployment. When automatically deploying through staging → production environments, the IP serves as the basis to:

• whitelist addresses on the firewall.
• Route traffic to the correct environment.
• Avoid wasting time when connection errors occur between servers.

Example: An internal eCommerce project in Ho Chi Minh City once encountered API connection errors due to misconfigured dynamically updated load balancer IPs. After integrating an automatic IP check step in the Jenkins Pipeline, the DevOps team reduced downtime handling time by 40% (Source: Internal Report, 2023).

Checklist: How to integrate IP checking into workflow

• ✅ Create a script to automatically check IP and log changes.
• ✅ Use a webhook to notify if the IP changes abnormally.
• ✅ Periodically update the IP whitelist on the server/cloud/firewall.
• ✅ Verify the domain points to the correct IP after each deployment.
• ✅ Attach IP check to the system monitoring software's Tag.
