Unlike datacenter proxies, residential IPs come from real devices. That makes them harder to be recognized and enables you to pick a specific location for targeting. They're a bit less stable and slower than IPs generated in servers because IP providers can hop in and off the network. However, they're also more block-resistant since they mimic real online behavior better.

Proxies can be compared from different angles depending on their direction, anonymity, protocol, etc. If we want to analyze them from the source perspective, we usually face three types of proxies: datacenter and residential. The latter is generated from real desktop, mobile, or other devices using Wi-Fi. Datacenter IPs are machine-baked proxies, usually from the same subnet, making them easier to recognize. They're also cheaper and faster, so they're still a good choice if you don't need an extensive targeting option.

You can easily select any location you want on the Smartproxy dashboard. Simply head to the left side and press “Endpoint generator” under the “Residential” toggle list. 

If you need to rotate your IP for each session and target areas in Vietnam, you must choose a specific domain:port combination and use the selected city or county's unique endpoint (in this case, Vietnam).

Yup, purchasing and using proxies from Vietnam is legal. You can use proxies for data gathering, verifying ads, monitoring SEO, etc.

However, you cannot use proxies for some cases like scraping governmental sites, ticketing, mailing, or streaming. There's quite a list of illegal activities not supported by ethical providers like Smartproxy. We are serious about blocking potentially fraudulent activities and only support legal and non-harmful activities with our proxies.
