Mastering WebRTC control to prevent browser privacy leaks
Using a VPN or proxy doesn't always guarantee that your real IP address stays hidden. Without proper WebRTC control, your browser may still expose network information that websites can use to identify you.
In this guide, IPFighter explains what WebRTC control is, how it works, and the best ways to prevent WebRTC leaks across different browsers. Show more
What is a localhost IP? Understanding 127.0.0.1 in development
Many developers and beginners often encounter the term localhost IP address when working with tools like XAMPP, Docker, Node.js, or local web servers. At the same time, many users are confused when they can't access their locally hosted websites or don't understand why the 127.0.0.1 address keeps appearing during development.
In this guide, IPFighter explains what a localhost IP is, how 127.0.0.1 works, why localhost is important in modern web development, and how to troubleshoot some of the most common localhost connection issues. Show more
WebRTC leak: Why your real IP address may still be exposed
Have you ever connected to a VPN only to discover that websites can still see your real IP address? Many users assume that enabling a VPN or proxy completely hides their identity, but that's not always the case. A feature built into modern web browsers called WebRTC can sometimes bypass these protections and expose information you intended to keep private.
In this guide, IPFighter explains what a WebRTC leak is, why it happens, what information it can expose, how to detect it, and the best ways to prevent it from compromising your online privacy. Show more
Understanding DNS forwarding for network optimization
Why does one network load websites almost instantly while another takes noticeably longer, even though both use the same internet connection? One reason is how DNS requests are handled behind the scenes. Many businesses and organizations improve both speed and security by using DNS forwarding.
In this guide, IPFighter explains what DNS forwarding is, how it works, why organizations use it, and how it helps optimize DNS performance while reducing security risks. Show more
DNS records - The ultimate blueprint for website & email routing
Have you ever wondered how a domain name knows where to send visitors, emails, or online services? The answer lies in DNS records - the instructions that tell the internet how a domain should function. From connecting websites to servers and routing emails to verifying domain ownership, DNS records play a critical role in keeping online services running smoothly.
In this guide, IPFighter explains what DNS records are, how they work, the most important record types, and how to configure them correctly. Show more
DNS leak: The silent threat to your online privacy
Are you using a VPN or proxy but still being detected, blocked, or having access restricted by websites? In some cases, the problem may not be your IP address but rather a DNS leak exposing your connection information.
In this guide, IPFighter explains what a DNS leak is, how it happens, the risks it creates, and how to prevent it. Show more
What is a virtual IP? Understanding VIPs in networking
Every networked device requires an IP address to communicate with other systems. Traditionally, an IP address is assigned directly to a physical server, router, firewall, or workstation. However, modern enterprise networks often require much higher availability, scalability, and fault tolerance than a single device can provide.
This is where a virtual IP (VIP) becomes useful. Instead of being tied to one physical device, a virtual IP can represent an entire service, cluster, or group of servers. In this guide, IPFighter explains what a virtual IP is, how it works, why organizations use it, and how it differs from traditional physical IP addresses. Show more
How to warm up IP address: Why new IPs need reputation building
Every new IP address starts with little or no reputation. Because security systems have no historical data to evaluate, new IPs are often treated more cautiously than established ones.
This is why many organizations choose to warm up IP address before using it for large-scale email campaigns, account management, or other online activities. By gradually increasing activity over time, an IP can build trust and develop a positive reputation. In this guide, IPFighter explains what it means to warm up an IP address, why it matters, and how to do it safely. Show more
What is an ASN lookup? How to track autonomous system numbers
Every IP address on the Internet belongs to a larger network operated by an ISP, cloud provider, hosting company, or enterprise organization. ASN lookup helps identify which network owns a specific IP address and provides valuable information about its infrastructure and routing.
But what exactly is an ASN, and why is ASN data important for network analysis, cybersecurity, and proxy verification? In this guide, IPFighter explains what ASN lookup is, how it works, and the practical ways it can be used to investigate network ownership and Internet infrastructure. Show more
IP whitelisting: The gatekeeper of network security
One of the most widely used methods for protecting sensitive resources is IP whitelisting, a simple but highly effective security mechanism that restricts access to approved IP addresses only. So what exactly is IP whitelisting? How does it work, and why do so many organizations use it to protect their systems? Let's explore the answers with IPFighter in the guide below. Show more
How to find out someone’s IP address
"How do I find someone's IP address?" is a question that receives a lot of searches and discussions in the tech and social media communities. Many users are curious whether determining someone else's IP address is actually possible and what information can be obtained from it.
In this guide, IPFighter explains how IP address tracking works, common methods used to identify IP addresses, the risks involved, and how users can better protect their online privacy. Show more
How public IP addresses work on the internet
Public IP addresses play a crucial role as a global identifier for your network connectivity. They enable routers, servers, and online platforms worldwide to exchange information accurately and efficiently.
In this guide, IPFighter explains what a public IP address is, how it works, the difference between public and private IPs, and how to check the quality of your IP address for safer internet usage. Show more
