Datacenter Hosted Proxy 
These are proxies physically located on server hardware in datacenters. Their IPs do not change during the entire rental period (a month or longer). They are the most prompt, stable, and cheapest proxies. When it comes to datacenter hosted proxies, proxy providers do not charge a fee for the traffic volume that a client generates while using the proxy service. The client pays only for the number of IP addresses that he receives. The datacenter proxies have a little poorer trust rate compared to residential and mobile proxies.
- Virgin (Never Used Before) Proxy
This is a proxy with a new IP address that was never used as a proxy server before. The virgin proxy is the least likely to be banned on the target website and the most expensive among all Datacenter Hosted Proxies. - Private (or Dedicated) Proxy
This is a proxy with an IP address that was previously used as a proxy. It may be accessed only to one proxy service client during the entire period of use. The private proxy is more likely to be banned on the target website than the virgin proxy. - Shared (or Semi-Dedicated) Proxy
The IP addresses of such proxies can be used by several proxy service clients at the same time. The likelihood that the IP addresses of the shared proxies may be banned on the target website is greater than the IP addresses of the private proxies and certainly the virgin proxies. - Rotating
This is one of the types of shared proxy which differs from it only in that a user can switch the IP address after a certain period.
Mobile Proxy 
These are proxies physically located on LTE / 4G mobile routers with SIM cards of mobile operators from different countries that are controlled by proxy providers. Depending on the features offered by a particular provider, the proxy service client can configure the frequency of IP change, select a specific mobile operator and geolocation. Depending on the conditions of a particular mobile proxy service, the client may be charged a fee for the traffic volume that he used. GNAT technology provides mobile proxies the highest trust rate among all types of proxies.
Residential Proxy 
These proxies are physically located on individuals' mobile and fixed devices (PCs/laptops, Wi-Fi routers, and mobile devices). A residential proxy' feature is that it has available a huge number of IP addresses distributed all around the globe. A client of such a service can finely configure the required geolocation up to a particular city, type of storage media device, Internet provider, etc. Most often, the residential proxy service client pays not for the number of received IP addresses, but for the traffic volume he used. The trust rate of residential proxies may be quite high. But their weakness is that they are a little less stable than datacenter hosted and mobile proxies.
- Rotating (Dynamic) Residential Proxy
These are dynamic proxies with the frequency of IP address change from several seconds to several minutes or until a user refreshes a page. The proxy service user can optionally choose the Sticky IP feature when he needs to have the current IP address for a longer period. - ISP (Static) Residential Proxy
These are static proxies by default. However, as a rule, a user can change the current IP address to another when he needs to.
Geo 
The proxy-server IP address is tied to a specific country according to the RIPE Registry.
Protocol 
This is a protocol supported by this proxy server. Before purchasing a proxy, please make sure that your bot or other application supports this protocol.
- HTTPS
Here, we mean both HTTP and HTTPS. - SOCKS5
This means that a proxy provider supports not only SOCKS5 but also its previous versions SOCKS4 and SOCKS4a.
Authentication 
Unlike free proxy servers, these proxy servers require authentication.
- IP
A proxy user is authenticated by his IP address. - U/P
A proxy user is authenticated by his username and password.
