Every user that connects to the internet has an IP address. These addresses are used for locating websites, identifying devices, and finding their geographic location. They are also used to determine the intentions of the users.
How can I check the reputation of an IP?
Using an IP reputation lookup tool can help you identify blacklisted IPs. This can be a helpful way to prevent spam.
An IP reputation lookup tool can be used to check any IPv4 or IPv6 address. Some of the tools available include MultiRBL, BrightCloud, and Talos Intelligence by Cisco.
The IP reputation lookup tool can detect malicious IP addresses that are sending out high volumes of spam. It can also identify open proxies and machines that should not be sending mail. A negative IP reputation can affect a user’s browsing experience.
If a user has a tarnished IP reputation, they should contact their ESP for further assistance. They can also try to clean up past issues.
Some lookup services offer a contesting feature, wherein the user can challenge a score that has been given to their IP. However, the results cannot be guaranteed.
A blacklist service can provide you with a list of IPs that have been blocked by Internet Service Providers (ISPs). There are some services that block entire neighborhoods of IP addresses. While it can be helpful to block bad actors, if an IP address is frequently associated with malware, it can lead to a poor reputation.
You can find an IP reputation lookup tool on many of the popular web sites. Checking your IP for a negative reputation can help you avoid online purchases.
