ISP
What is an ISP?
An ISP, or Internet Service Provider, is a company that provides internet access to individuals and businesses.
To browse the web, you need to pay an ISP for internet access, usually through a monthly subscription or prepaid data passes. Therefore, they act as the gateway to the internet for all users, enabling activities like streaming videos, searching for content, checking email, shopping online, making video calls, and accessing FTP servers.
1. Types of Internet Service Providers
ISPs offer various types of internet access, such as ADSL, cable, satellite, or the most widely used today, fiber optic. Here are some common types of ISPs:
- Dial-up ISPs
These were the most common years ago, providing network access through a phone line and a modem. They offer the slowest and cheapest connections, but this type of service is now obsolete following the rollout of fiber optics and faster alternatives. - DSL ISPs
This service provides high-speed modem connections using the copper wiring found in most homes. The connection speed is high, but it heavily depends on the physical distance between the home and the ISP’s local exchange. - Cable ISPs
These providers offer internet access through a coaxial cable (the same one used for TV signals). Just like the previous options, a modem is required. - Fixed Wireless ISPs (Wireless Broadband)
This service is provided in remote, hard-to-reach areas where cable infrastructure doesn’t exist. ISPs use radio frequency antennas to deliver their services (common in rural areas and usually at a higher cost). - Satellite ISPs
In this case, the ISP uses wireless satellite connections to provide internet service in remote locations (without antenna or cable infrastructure). These satellite connections usually offer fast download speeds, but upload speeds are typically very slow. - Fiber Optic ISPs
Currently, this is the most popular connection type for both businesses and individuals in urban environments. It allows for extremely high connection speeds, and a single fiber optic cable can serve multiple customers.
2. The Difference Between an ISP and a Hosting Provider
Besides internet access, ISPs usually diversify their business and commonly offer additional services to their customers, such as cable television. To a lesser extent, they offer web hosting services, but people often confuse an ISP with a hosting provider.
As a general rule, a hosting provider doesn’t offer ISP services, but an ISP does occasionally provide hosting services.
On the other hand, hosting companies are themselves customers of ISPs, connecting their network infrastructure to one or more ISPs to serve their own clients (who primarily host their websites on the hosting provider’s servers).
3. How do I find out who my ISP is?
To find out who your ISP is, you just need to check the bills you pay for your web hosting service. But if you don’t have that handy, you can easily identify your ISP using a web browser.
Simply visit any of these websites: whoismyisp.org, spyber.com, or ipcheck.org, and they will automatically reveal complete information about your internet connection, including your ISP. You’ll generally find it listed as: ISP:, My ISP:, or Organization:.
