IP REPUTATION CHECK




IP ADDRESS REPUTATION LOOKUP & API





Your IP address is: 5.187.21.105



Use this free tool to accurately check IP Reputation using leading IP address
intelligence. Lookup IP reputation history which could indicate SPAM issues,
threats, or elevated IP fraud scores that could be causing your IP address to be
blocked and blacklisted.

The most common reason for elevated IP risk scores is due to previous abusive
behavior from the IP address. This could include sending SPAM, compromised
devices, or any form of suspicious behavior. High risk connections such as
Proxies & VPNs can also negatively impact IP address reputation. Perform
real-time checks using our IP address reputation API.


ACCURATELY CHECK IP REPUTATION HISTORY



Millions of the internet's most popular sites use IP reputation to detect bots,
block email SPAM, prevent fake registrations, and verify users or payments. IP
Reputation is so important, that it can cause your company's email to
automatically go to the spam folder by triggering spam filters, prevent
purchases online through fraud prevention measures, or even block your login to
Netflix or Hulu.

IP address reputation is based on the neighborhood of your IP address, such as
if it's registered to a data center, hosting provider, residential or wireless
network. Some services outright block entire neighborhood's of IP addresses due
to poor IP reputation or if many addresses within that subnet are frequently
engaging in suspicious behavior which produce high IP fraud scores. Your IP's
threat status as seen by major brands online is also determined by these
factors.

IP reputation history also plays a major factor in the IP's current risk score.
Proxy & VPN IP addresses or any that allow anonymized connections to be tunneled
through their network can invite bad actors such as cybercriminals or
fraudsters. These users tend to abuse IP addresses by committing fraud or
abusive behavior which has a negative impact on the IP score. IP reputation
services monitor abuse reports through IP history events and online behavior to
identify blacklisted IPs.


IP Reputation Use Cases


Lookup IP Reputation for any IPv4 and IPv6 address with worldwide coverage by
using the tool on this page or our IP reputation API. Continue reading below to
learn more about how to remove your IP address from blacklists that could be
hurting IP reputation scores. Alternatively, you can also check domain
reputation using leading data by IPQS.

IP REPUTATION SCORES EXPLAINED



Fraud prevention companies assign an IP risk score which can be used to analyze
user quality. IP fraud scores are usually calculated during registration, login,
or when making purchases online. IP address risk scores are elevated whenever
malicious behavior online is reported through a honeypot trap or if a site
automatically reports feedback to a blacklist provider. Our IP reputation
service tracks recent abuse reports through our vast network of IP address data.
Multiple abuse incidents in a short period of time will indicate higher IP risk.




WHAT IS IP ADDRESS REPUTATION?



IP reputation can best be explained as the estimated behavior quality exhibited
by an IP address. IPs frequently used by bots, fraudster, or cybercriminals will
naturally have much lower IP reputation (and higher IP risk scores) than an
address used for legitimate browsing behavior online. IPQS translates internet
protocol (IP) reputation history into an intelligent IP address fraud score.
Since every user browsing a site has an IP address, it is the quickest way to
determine a user's intentions.




HOW CAN I IMPROVE IP REPUTATION?



It is common for users that have recently taken over a new IP address with a
tarnished reputation to cleanup past issues. First, identify which blacklists
your IP address is currently blocked on. The free reputation lookup tool above
will identify specific IP blacklists that currently list your address. It is
also recommended to use the bot IP address check to detect if the IP has been
compromised or used by malicious bots.

Each of these blacklist services offers a way to delist IP addresses in their IP
reputation database. Navigate to the site(s) where your IP address is
blacklisted and follow their process to delist. Most services will delist IP
addresses within 24 hours of the request, which can lower your IP fraud score
across popular online services. It is important to maintain healthy reputation
once your IP address has been removed from any blacklists, since repeat entries
into these blacklists may hurt your chance of getting delisted in the future.




QUICK GUIDE TO MANAGING IP REPUTATION



If you are sending marketing or transactional email from your IP address, it's
best to use an email address validation service to scrub invalid emails from
your marketing lists. Low bounce rates will ensure that mail service providers
do not blacklist your IP address or negatively impact the IP fraud score.
Regular email cleaning will also remove spam traps and spam complainers that can
add your IP address to third party blacklists.

If you are using your IP address for routine browsing rather than sending email
messages, then not acting suspiciously online is the best advice for managing IP
reputation and maintaining a healthy IP fraud score for your connection. Provide
real information on registration forms, avoid creating duplicate accounts, and
stay away from hacking or website attacks as honeypot traps can quickly add your
IP address to active blacklists.

TOOLS TO MONITOR IP REPUTATION



In addition to using the IP address reputation lookup tool on this page,
MultiRBL provides a great free service for checking IP health. MultiRBL checks
over 200 mail server blacklists and currently supports both IPv4 and IPv6
addresses. If you having issues with your IP reputation score for email
marketing then you can also use our email spam checker to test your messages for
reputation issues. Using an IP reputation API service is the most effective way
to monitor IP reputation for any changes in risk scoring.




IS AN IP REPUTATION LIST AVAILABLE?



IPQS monitors over 4 billion IPv4 addresses and hundreds of billions of IPv6
addresses in today's ever changing threat climate. With such a large amount of
data, we recommend using our IP Reputation API to analyze ip risk. An IP
reputation database solution is also available for download to perform
on-premise IP fraud score lookups.

Please reach out to our team to inquire about our downloadable IP reputation
list or locally hosted database.




IP WARMING BEST PRACTICES



Warming up IP addresses is a best practice for any use case involving email
marketing or transaction email sending. During an IP warm up period, email
sending volume is slowly increased. This allows sending patterns to appear more
natural to mail service providers and anti-spam services. The recommended
schedule for an IP warm up strategy is to start with a maximum of 50 emails per
day to avoid spam filters, and then double that value every 3 days. This
schedule provides the best opportunity to maintain healthy IP reputation while
avoiding blacklists.
