IP to ISP Lookup
An IP to ISP lookup tool helps you figure out which internet service provider (ISP) is behind a specific IP address.
What is ISP?
ISP stands for Internet Service Provider, which is a company that provides internet access and network connectivity, Examples include home broadband companies, mobile data providers, and enterprise network providers.
Public IP addresses are assigned by ISPs to devices directly connected to the internet, allowing them to communicate with other devices across the globe. Many ISP providers also offer extra ISP services, such as business internet, dedicated lines, DNS hosting, and more.
An IP to ISP lookup doesn't give every provider in one place, but it can:
- identify the provider tied to an IP,
- show the organization/network name,
- help you compare patterns across many IPs.
Why do an ISP Lookup for an IP?
- Detect suspicious traffic faster: If you're dealing with spam, scraping, brute-force attempts, or weird signups, checking isp lookup helps you understand where the traffic is coming from. IP address lookup can be used for security purposes, such as tracking spammers and hackers.
- Block or allow traffic more intelligently: Some teams allowlist/denylist based on certain ISPs, regions, or network types. An ip to isp lookup is often a first step before deciding what to do.
- Investigate fraud and abuse: Fraud patterns can show up from certain networks or hosting providers. An isp lookup by ip makes investigations easier.
- Improve support and troubleshooting: If a user says "my site is slow", knowing their ISP can help you spot routing or provider-related issues.
- Understand traffic quality: For marketers and product teams, isp providers and network types can hint whether traffic looks like real users, bots, or data-center traffic. ISPs also use customer data for regional profiling and marketing insights.
ISP Proxies and why they matter
You'll often hear the term ISP proxies in security and automation discussions. These are proxies that route traffic through IPs that appear like regular residential or consumer ISP addresses and because of that, they can be harder to detect than basic hosting proxies.
There are mainly three types of ISP Proxies:
A) Static ISP proxies
- Same IP stays assigned for long periods.
- Used for account management, long sessions, fewer logins.
- Higher reputation risk if abused (because the IP doesn't change).
B) Rotating ISP proxies
- Provider rotates you across a pool of ISP-like IPs.
- Used for scraping, high-volume tasks.
- Rotation patterns can look bot-like if too frequent.
C) Geo-targeted ISP proxies
- City/region/ISP targeting (e.g., "Lahore ISP", "NYC ISP").
- Used for geo testing, ads verification, localized content.
