How to Identify Your ISP and Understand IP Addresses
Determining your Internet Service Provider (ISP) is crucial for understanding the services you use and optimizing your online experience. Here’s a comprehensive guide on how to find out who your ISP is and what you need to know about IP addresses.
Identifying Your ISP
Your ISP is the company you pay every month for your internet connection. However, understanding your ISP involves more than just knowing the company name. It often helps to understand the IP address provided to your modem or router by your ISP, which is the key identifier providing access to other networks.

Method 3: Contact Building Management

Online Search for ISP Coverage
You can also perform an online search using your address to find out which ISPs service your area. This can help you determine the available options and potentially choose an ISP.
Understanding IP Addresses
Your ISP obtains IP addresses from a Regional Internet Registry (RIR). For instance, if you are in Europe, the RIR is RIPE (Réseaux IP Européens). You can use their website to look up number assignments, which can help you identify which blocks of numbers are assigned to your ISP.

Your ISP might have multiple IP addresses, depending on their network configuration. Understanding these can be crucial:
Your ISP's blocks of IP addresses: Consider your ISP's ASN (Autonomous System Number), which simplifies the process of looking up their IP assignments. Subnet masks: Your ISP's IP addresses might be spread across multiple subnets. This can involve a significant number of addresses, potentially in the billions, based on network configurations. External IP Addresses: Depending on your ISP, they might have hundreds or thousands of external IP addresses, primarily for internet-facing services.Important DNS IP Addresses
Beyond the IP addresses provided to the modem or router, your ISP's DNS servers are also crucial. These servers are stored in the memory of your device and are used to look up your internal IP address, such as for your home network.
Primary and Secondary DNS IP addresses: These are the actual IP addresses of your ISP, unless manually set otherwise. Using these DNS servers helps you access your ISP's content while appearing to be connected from any location. Utility of DNS IP addresses: While not all IP addresses are commonly useful, these DNS addresses hold significant value. They are used by streaming services like Netflix to identify your ISP and location accurately.In summary, understanding your ISP and IP addresses is essential for optimizing your online experience. Whether it’s about identifying your ISP or understanding the nuances of IP addresses and DNS, these details can provide valuable insights into your internet services.
