Commercial (COM)

Commercial networks are operated by for-profit businesses ranging from local startups to multinational corporations. These IPs facilitate e-commerce, internal corporate operations, and general business activities aimed at generating revenue.

Mobile ISP (MOB)

Mobile network operators provide internet connectivity via cellular technologies such as 4G and 5G. These IPs are primarily used by smartphones, tablets, and IoT devices, offering flexible access for users on the move. They are characterized by wide geographic coverage and the ability to handle high volumes of roaming traffic.

Search Engine Spider (SES)

Search engine spiders are automated bots and crawlers used by companies like Google or Bing to index the web. These IPs belong to scripts that scan public-facing websites to analyze content and update search results. While they represent automated traffic, they are essential for the discoverability of information on the internet.
