What is a Proxy ISP? What is a dual ISP?



A proxy is an intermediary server that routes internet traffic. Proxies are typically categorized into two types: data center proxies and residential ISP proxies. So, what is a Proxy ISP? How is a dual ISP different? Let's explore this with TotHost!

What is a Proxy ISP?

A proxy ISP is a server with an IP address assigned to users by an ISP. These ISPs do not include end-user devices like desktop computers or mobile phones. Instead, proxy ISPs are placed on servers and have static characteristics in terms of proxy ports and session types.

For this reason, a proxy ISP is also called a Static Residential proxy.

How does a Proxy ISP work?

In reality, a proxy ISP is considered a blend of data center proxies and residential ISP proxies, addressing their disadvantages and providing benefits in terms of both speed and security features:

  • The prominent advantage of data center proxies is their network speed and stability. However, this type of proxy does not truly resemble a real user's network, making it easily detectable. On the other hand, a Proxy ISP relies on IP allocation capabilities tied to specific locations of ISPs, providing you with a legitimate and unique IP address that helps conceal your actual location.

  • Residential proxies can ensure that your browser appears as a regular user, helping you avoid detection and access restricted content. However, since they are dynamic proxies, they are often blacklisted. Static residential proxies with fixed IPs are less likely to be blacklisted. 

    What is a Dual ISP Proxy?

    If you have ever used an ISP proxy through Ipinfo or Whoer, you might have come across the term “dual ISP proxy” several times. Dual ISP is mainly identified by the “type” information in two sections:

  • ASN (Autonomous System Number)
  • Company
  • A Dual ISP will have the “type” as ISP in both the ASN and Company fields. In contrast, a single ISP will have the ISP type in only one of these fields. If neither the ASN nor the Company is an ISP, it is not an ISP proxy.

Where can you buy Dual ISP IPs?

At TotHost, you can purchase Dual ISP IPs for the TOT M VPS packages.

When purchasing a dual ISP IP, you will need to pay an additional 80,000 VND/IP (~$3.25). Tot will fully support setting up the IP on your VPS for free within 12 to 24 hours. All you need to do is just create a ticket request for Dual ISP IP.

What can Static Residential Proxies be used for?

As mentioned above, ISP proxies combine the speed advantages of data center proxies with the “anonymity” features of residential proxies. Notably, these static residential proxies are less likely to be blacklisted compared to regular residential proxies. Here are some tasks that require an ISP proxy:

  • Web Scraping: Web scraping involves extracting large amounts of data in a short period. Therefore, ISP proxies, with their fast and stable connections, are very suitable for web scraping. Their anonymity and static IP address make ISP proxies the optimal choice for accessing data consistently from a specific location.
  • Bypassing Rate Limits: To prevent cyber-attacks like DoS, many websites and data centers implement rate limiting. ISP proxies provide ISP addresses that help bypass rate limit codes, making your requests appear more like those from real users and reducing the risk of being blocked.
  • Accessing Geo-Specific Content: Some content is blocked in certain geographical areas but is accessible elsewhere. To view such content while in a restricted location, simply use a proxy to change your location. Like all other types of proxies, ISP proxies allow us to change our virtual location. This way, you will be perceived as a real user in another country/region and can freely access location-specific content.
  • Bulk Purchasing on E-commerce Sites: E-commerce sites often block automated purchasing by bots. With an ISP proxy, you can bypass this restriction and make bulk purchases.
  • Monitoring SEO Activities: Search engine results and ad displays can be influenced by your location and browser cookies. To avoid these issues, you can use an ISP proxy to anonymize your connection or simulate users from different global locations.
  • Supporting Social Media Activities: Managing multiple media accounts with the same IP address can attract attention. In such cases, ISP proxies can be particularly useful as they can bypass social media algorithms related to IP addresses, reducing the risk of being blocked.

In summary, ISP proxies offer numerous advantages. However, when choosing an ISP proxy, to ensure your security, make sure to consider the “purity” and exclusivity of the IP.
