IP Filtering

How IP Filtering Works

IP filtering operates by analyzing incoming traffic to identify and block IP addresses that exhibit behaviors associated with click fraud. This involves monitoring click patterns and assessing the geographical location of IP addresses. When suspicious patterns or non-originating traffic is detected, the system can automatically block these IPs from accessing advertisements. This proactive protection minimizes wasted ad spend and delivers high-quality leads.

Types of IP Filtering

• Blacklist Filtering. This method involves maintaining a list of known fraudulent IP addresses. Whenever a traffic request comes from an IP on this list, it is automatically blocked from accessing the ad or website.
• Whitelist Filtering. This approach allows only specific, trusted IP addresses to access certain resources. It is effective in environments with known user bases, reducing the risk of malicious traffic.
• Geo-Blocking. Geo-blocking restricts access based on geographical location. Advertisers can prevent clicks from countries where they do not deliver services, thus reducing the risk of fraud from foreign IP addresses.
• Dynamic Filtering. This technique continuously updates IP filtering rules in real-time as new fraudulent behavior is detected. It adapts to emerging threats quickly, maintaining campaign integrity.
• Behavioral Filtering. This type uses machine learning algorithms to analyze user behavior patterns. It identifies anomalies indicative of fraud, such as sudden spikes in clicks from a single IP, leading to its temporary or permanent blocking.

Algorithms Used in IP Filtering

• Threshold-based Algorithm. This algorithm triggers blocking when click counts exceed a defined threshold for a single IP address in a timeframe, indicating possible bot behavior.
• Rule-based Algorithm. It uses predefined rules to evaluate traffic patterns, identifying and blocking IPs that match criteria associated with click fraud.
• Machine Learning Algorithm. This advanced technique utilizes historical data to predict and detect fraudulent clicks, continually learning from new data to enhance accuracy.
• Anomaly Detection Algorithm. This algorithm monitors user behavior and flags any deviations from typical patterns, alerting for potential fraud.
• Geolocation-based Algorithm. It checks the geographical origin of clicks, blocking those from high-risk regions or those that do not align with the target audience.

Industries Using IP Filtering

• Advertising Industry. Advertisers use IP filtering to protect their budgets from click fraud, ensuring authentic user engagement with their ads.
• eCommerce. Online retail businesses utilize IP filtering to secure transactions and prevent fraudulent orders originating from suspicious IP sources.
• Financial Services. Banks and financial institutions rely on IP filtering to safeguard transactions, preventing unauthorized access from fraudulent IPs.
• Gaming Industry. Gaming companies implement IP filtering to combat click fraud in in-game purchases and account creations, protecting their revenues.
• Travel and Hospitality. Travel websites use IP filtering to block fraudulent bookings made with stolen credit card details from risky locations.

Practical Use Cases for Businesses Using IP Filtering

• Ad Campaign Protection. Businesses can filter out fraudulent clicks, ensuring that their advertising budget is spent efficiently on real potential customers.
• Secure Transactions. By blocking suspicious IPs, businesses can shield their payment gateways from fraudsters during online transactions.
• User Data Protection. IP filtering helps to maintain the integrity of user databases by preventing malicious access attempts from spoofed or risky IP addresses.
• Reduced Ad Spend Wastage. Companies can improve their ROI by focusing ad spend on legitimate traffic, minimizing losses to click fraud.
• Competitor Blocking. Businesses can use IP filtering to block clicks from known competitors attempting to deplete their ad budgets through fraudulent activities.
