When diagnosing connectivity issues or verifying how a machine is exposed
to the internet, IP lookup tools are often used as a first step. These tools
display the public IP address seen by external services and may provide
additional context such as network ownership or reputation indicators.
Below is an overview of commonly used IP lookup websites and the typical
scenarios where they are applied.
MyIPNow
MyIPNow is a browser-based utility that displays the current public IP address
for a connection and supports both IPv4 and IPv6. It also provides related
network tools such as DNS lookup, WHOIS queries, IP blacklist checks, basic
internet speed testing, and a client-side password generator.
The tool is commonly used as a quick external visibility check before
performing more detailed network diagnostics.

WhatIsMyIPAddress
WhatIsMyIPAddress is one of the most widely recognized IP lookup services.
It reports the public IP address associated with a request and includes
approximate geolocation, ISP information, and proxy-related indicators.

IPinfo
IPinfo provides structured IP and network metadata and is frequently used
by developers via its API. Typical use cases include log enrichment,
geolocation analysis, and ASN identification.

IPLocation
IPLocation aggregates geolocation data from multiple providers, making it
useful for comparing how different databases resolve the same IP address.

IPVoid
IPVoid focuses on IP reputation and security-related checks, including
blacklist status and domain reputation analysis. It is often used when
investigating email delivery problems or potential abuse.

WhoisXML API
WhoisXML API offers access to WHOIS and IP ownership data in structured
formats. It is typically used in professional or automated environments
rather than for casual lookups.

DNS Checker
DNS Checker is commonly used alongside IP lookup tools to verify DNS
resolution and propagation across multiple geographic locations.

Summary
IP lookup tools serve different purposes, ranging from simple IP visibility
checks to reputation analysis and structured data access. Because data
sources and interpretation vary, combining results from multiple tools
often provides a more accurate understanding of a network issue.
