Whether you’re running a small business or a large enterprise, ensuring that your website and emails are trusted by users and other companies is key to maintaining credibility. One major issue that can harm your reputation is ending up on a DNS blacklist. If your IP address is blacklisted, it can prevent your emails from reaching customers, affect your site’s visibility, and tarnish your brand.
This blog will guide you through DNS blacklisting, why it’s problematic, and how to get delisted if you find yourself on one. We’ll also introduce Dotcom-Monitor’s DNS blacklist monitoring service, which can help keep your business safe from reputation damage.
What is DNS Blacklist?
A DNS blacklist, or Domain Name System blacklist, is a database of IP addresses that are suspected of spamming, distributing malware, or engaging in other harmful activities. Various organizations and ISPs (Internet Service Providers) manage DNS blacklists to help block unwanted or harmful internet traffic. They use automated systems to add IPs to blacklists based on criteria such as:
- Sending high volumes of unsolicited emails
- Detected malware or suspicious activity
- User complaints about spam
DNS blacklists are a safeguard, but they can also catch innocent parties in their net. If your server has been hacked or your network has been used to send spam, for instance, your IP might end up on one of these lists, even if it’s unintentional.
How does DNS Blacklist work?
DNS blacklists work by associating specific IP addresses with unwanted or malicious behaviors. When an email is sent from an IP address, the recipient’s email server checks the sender’s IP against various DNS blacklists. If the IP is on a blacklist, the server may block the email or mark it as spam, preventing it from reaching the recipient’s inbox.
For websites, being on a DNS blacklist can impact SEO and overall online visibility, as some search engines use blacklists to flag websites suspected of distributing harmful content.
The process goes something like this:
- Automated Detection or User Reports: DNS blacklists use automated systems to scan for suspicious activity and IPs associated with spam or malware. Users and businesses can also report suspected IPs.
- Blacklist Verification: After verification, the IP address is added to the DNS blacklist.
- Blacklist Check by ISPs and Servers: When an email or web request is made from a blacklisted IP, ISPs and servers can detect this and either flag or block the content.
Why is Being on a DNS Blacklist Bad?
Being on a DNS blacklist can harm a business in several ways. Here’s why it’s crucial to stay off these lists:
1. Email Deliverability Issues
When your IP is on a DNS blacklist, many email servers will automatically block emails coming from your domain or send them to the spam folder. This means your important communications, promotions, and customer service emails may never reach your clients. Over time, this can erode trust and even result in lost revenue.
2. Damage to SEO and Online Reputation
Search engines also use DNS blacklists to identify sites that may distribute harmful content. If your website is flagged, you could experience reduced search visibility, leading to decreased traffic and a hit to your online reputation.
3. Loss of Customer
Trust If customers find out that your domain is associated with spam or malware, their perception of your business can take a serious hit. Maintaining a good online reputation is key to retaining customers and attracting new ones.
4. Reduced Network Performance
Being on a DNS blacklist can also strain your network, as filtering and routing rules might be applied to your traffic, slowing down service. Over time, this can affect the quality of service for your users or customers.
Getting Delisted from the DNS Blacklist
The moment a company realizes that they’ve been added to the DNS blacklist, immediate measures should be taken to get delisted and get back to business. First of all, there are online tools that could help the business understand if it has been blacklisted or not.
How does that work? This is a test that would prompt the user to insert a hostname or an IP address. It performs a check against all the databases that could have blacklisted the IP. This can give the company a clear idea of the status of the mail servers. But even before that, the absence of customer replies or a reduction in website traffic could be a key indicator of being blacklisted.
Once the test is conducted, the next step requires the company to take the necessary actions to delist the IP address. This would include figuring out which sites have blacklisted the company IP and then contact them individually. Every blacklisting site has its own protocol and procedure to delist IP address from their blacklist. In most cases, they would provide a form to the blacklisted IP, requesting information for removing the address.
However, it’s essential to figure out the main cause that prompted the server to get blacklisted in the first place, and get it resolved before submitting the delisting application. This is where DNS Blacklist monitoring plays an important role. This continuous tracking process can help maintain the company’s reputation amongst the site visitors and other internet users.
