Ensuring your IPv4 addresses are clean is vital for maintaining network integrity, avoiding blacklists, and ensuring smooth email deliverability. If you’ve ever found yourself in a situation where you feel like you need to check on the status of your IPv4 addresses, or new ones you are about to purchase, here are some helpful hints.

Assessing Your Current IPv4 Addresses

Ensuring the cleanliness of your current range of IPv4 addresses is essential for maintaining network integrity and avoiding potential issues such as blacklisting or reduced email deliverability. Regular assessments help identify and address problems early, ensuring smooth and uninterrupted operations. Here’s how you can effectively evaluate the status of your current IP addresses.

  1. Blacklist Checks Regularly check if your IPv4 addresses appear on blacklists using a tool like MXToolbox, which is great for checking on individual IPv4 addresses. Blacklisting usually indicates that the IPv4 address has been flagged for spam or malicious activities.
  2. Reputation Services Use services such as Cisco Talos to assess the reputation of your IPv4 addresses. These services provide insight into whether your IPs are associated with spam or other malicious behavior.
  3. Email Deliverability Monitoring Keep an eye on your email deliverability rates. High bounce rates or emails being marked as spam can be indicators of problematic IPv4 addresses. Tools like MailChimp or SendGrid offer deliverability monitoring features.
  4. Network Traffic Analysis Monitor your network traffic for unusual activity. Significant traffic spikes or unexpected patterns can indicate that your IPv4 addresses might be compromised or misused.
  5. Regular Audits Conduct regular audits of your IPv4 addresses. ARIN’s WHOIS database is a great option. These audits can help you maintain up-to-date information and quickly address any issues that come up.

Evaluating New IPv4 Addresses

Before integrating new IPv4 addresses into your network, it’s crucial to ensure they are clean and free from past issues. Proper evaluation helps prevent future problems, such as blacklisting or poor reputation. By conducting thorough checks and working with reputable brokers, you can confidently add new IPv4 addresses to your system. Here’s how to effectively evaluate the status of new IPv4 addresses before acquisition.

  1. Reputation Check Before Purchase Before purchasing new IPv4 addresses, use reputation check tools to ensure they have not been previously blacklisted or associated with malicious activities.
  2. Due Diligence with Reputable Brokers Work with reputable IPv4 brokers who provide transparent transaction histories and ensure the cleanliness of the IPv4 addresses. When you work with IPTrading, for instance, we check multiple blacklist sites to ensure clean and reliable IPv4 addresses.
  3. Ownership Verification Verify the legitimate ownership of the IPv4 addresses through registry databases like RIPE, ARIN, or APNIC. This step ensures that the seller has the right to sell the IPv4 addresses and that there are no legal issues.
  4. Historical Data Analysis Request historical data on the IPv4 addresses to check for any past issues. This data can reveal if the IPv4 addresses were previously used for spam or other malicious activities.
  5. Other Reputation Checks While email blacklists are the major concern of most IPv4 owners and buyers, there are other private blacklists used by various providers that check other attributes of IPv4 addresses, such as whether they have too heavily been used for proxy or VPN services.  IPTrading can help determine if your IPv4 addresses are at risk from other reputation attributes.

By taking these steps, you can ensure that both your current and new IPv4 addresses remain clean, maintaining the integrity and reputation of your network.
