DNSBL - What Is It?

DNSBLs, also known as Domain Name System Blacklists or Block Lists, allow web owners to filter out spam and unsolicited messages. As the name implies, these lists are built on the Internet's Domain Name System (DNS) which translates numerical IP addresses into domain names for easy reading, searching, and utilization.

IP addresses are used by blacklists to keep track of e-mail servers which have sent spam in the past. Any messages from that server will then either be flagged or blocked by sites using the same blacklist. With numerous options available, the criteria for inclusion varies; some maintainers may be more reliable than others.

In the past, DNSBLs were known as RBLs, and sometimes they are used interchangeably with DNSBLs when talking about spam blocking.

Tool For Blacklisting Search Engines

It is not desirable for a legit website to be listed on a search engine's blacklist. If a website is listed on any search engine's blacklist, it will cease to exist on the internet. Search engines blacklist websites for a variety of reasons. If a website is spamming, it will get blacklisted.

Suspicion of hacking or association with untrusted sites are common reasons for websites being blacklisted. Search engines thoroughly examine each website’s contents and links, and if any suspicious activity or bad links are found, the site will be blocked. A blacklisting renders the website invisible on the internet, as search engines use IP address to block access. Be aware that if your website is using a dynamic IP address and it is blacklisted by a search engine, any sites utilizing that same IP will also be blocked from view.

Use Of A Blacklist Lookup Is Important

A domain blacklist check is primarily used to block emails, so it is often used for that purpose. Most e-mail servers nowadays have DNSBL support either built in or as a plug-in which allows a server administrator to block all emails from domains or sites listed on a particular DNSBL. Recently, DNSBLs have also been used in spam scoring systems, such as SpamAssassin, as a way to minimize the amount of spam that users receive.

In the event that your name is on a spam blacklist and is also referenced in a spam scoring system, your spam score may be increased by some time. It could be discarded or sent to the spam folder if that, together with other scoring tests, results in a score above a certain level.

Blacklists For Smart Phones

Every day, thousands of smart phones are lost and stolen, and cell phone service providers are notified of these incidents. A smart phone owner who knows their phone's IMEI number and reports it will be blacklisted, so that the thief is unable to use the cell phone. When a smart phone is recovered from a lost or stolen state, the owner must report it to the cell phone service provider, who will remove it from the blacklist.
