What is IP Blocklisting?
IP blocklist is a list of IP addresses that are blocked due to some security reasons. Blocklists are lists comprising ranges of or an individual IP address that you want to prohibit. You can use these lists in combination with firewalls, intrusion prevention systems (IPS), and other traffic filtering software for security.
IP blocklisting, formerly known as IP blacklisting. IP blocklisting is a type of security measure to block access to network or single systems from specific IP addresses.
An IP blocklist can help figure out whether the resource is associated with, for example, spammers or cybercriminals.
Moreover, It is a mechanism used to filter out poor reputation, and unauthorized malicious IP addresses from accessing your networks. IP reputation indicates whether the device connected to the IP address is trustworthy or not. IP blocklisting is one of the simplest and most effective ways to deny the world of computers.
Why IP Blocklisting Matters?
Implementing IP blocklisting allows you to filter malicious or poor traffic according to policies or through the manual addition of IP addresses. Many network security tools or softwares that use blocklisting are also able to add new addresses to be blocked. This can be done as externally referenced lists are updated or according to the results of event analysis.
What Causes IP blocklisting?
IP addresses are blocklisted for various purposes. The purpose is to secure users and other websites from malicious IP addresses.
However, Blocklist occasionally includes other IP addresses mistakenly. A typical, secure IP is so prohibited. After that, a genuine user’s address will appear in an IP blocklisting even if they haven’t done anything illegal.
In any event, one of the following reasons is typically responsible for adding an IP address to an IP blocklist:
- When spam emails are intentionally sent.
- When the daily sending limit is exceeded.
- The recipient is marked as spam.
- Spam or malicious emails are sent using hacked mailing servers.
- After seizing control of a domain, cybercriminals used it for their own gain.
- Malware has been installed on one of the network users.
- The device has questionable software on it.
- The IP address is connected to a dangerous website that can be harmful.
- The IP address had been used unfavorably by a previous user.
What is IP Blocklist Check?
It is essentially an IP reputation check. The process shows whether an entered URL or IP address belongs to a domain name server blocklist (DNSBL).
There are numerous DNSBLs available online, and each has its own set of standards for listing and delisting IP addresses. But any IP that is listed by the DNSBLs is blocked from sending emails since the DNSBLs view any address on the lists as a source of spam.
Different DNSBLs are used by spam filters to confirm that incoming emails do not originate from sites that are blocklisted, which would be a warning sign.
In many cases, the first line of defense against IPs or domains delivering spam is these domain name server blocklists.
Nonetheless, the domain blocklist database occasionally adds addresses that don’t transmit
How to Check if Your IP is Blocklisted
There are several tools available dedicated to providing anti-spam and virtual reputation blocklists. They provide their own blocklists that help determine the overall reputation of an IP or domain.
Using these IP blocklist checking tools, you can access data regarding your IP address or domain status.
If you find that your IP address or domain was blocklisted with the help of these tools, your next step is to remove/delist the IP address from the blocklist. Because it may block your genuine users.
Check blocklists for your IP address by entering the address into the tool above. If you don’t know your IP address, the WhatisMyIPaddress homepage shows you your IP address and its details. It allows you conveniently copy and paste your IP into this tool to run a scan.
The IP blocklist checker tool will search IP blocklist sites and show a table of various blocklists. It lists the block status of each of your server IP addresses.
Domain name blocklists don’t notify users when their IP address goes on a blocklist. Users need to check name blocklists to find their status.
Therefore, blocklist checks are essential for users, mail servers, or businesses who believe that they have a blocklisted IP address. If your IP is blocked, you’ll show up on the list. Using the tool above is the easiest way to check for blocked IPs.
To check using any tool, if your IP address has been blocklisted, do following:
- Open the tool or the website you are checking on and enter your IP address in the Server IP or Domain field, and click blocklist/Blocklist Check.
- Your mail server IP will be checked against blocklists.
- If your IP address is blocklisted, you will receive a message and a list of blocklists.
- You can see the details for information about the blocklist, the reason for blocking, and possible ways to get delisted.
