NAT technology at home and mobile networks

30 March 2020

Astro is a trusted website where millions of people buy residential and mobile proxies. The key to our success is that our proxies use the issue of lack of real/white IPv4 addresses.

Users of home and mobile Internet receive ‘gray’ addresses of providers. This means that there are always a lot of users behind one white address of the provider. This is implemented through NAT (Network Address Translation). This technology is used to simplify and save IP addresses. NAT works on a router, which typically connects two networks, and translates private (rather than globally unique) addresses on the internal network into valid addresses before forwarding packets to the other network.

Home and mobile Internet (and most networks with a large number of users) are based on NAT technology, since each user cannot receive a white IPv4 address.

Remote sites cannot see the ‘gray’ addresses (the addresses which are located behind the NAT provider), they only see the white IP addresses of the provider.

Accordingly, a remote service, such as Facebook, LinkedIn, Instagram, Google, can easily block your ‘individual proxy for $10, ultra-white and good’, simply adding it to the IP blocking list (since this is just a server address that no one else uses). But this is not the case with residential IP addresses, because, if blocked, many users will suffer, not only the spammer/bot/account manager.

The so-called individual datacenter proxies are a relic of 2007. They may have worked best back then, but now they are not trusted and any large website will block an individual proxy, as it belongs to the datacenter/dedicated server/vds.

You can check your proxy type, your home or mobile IP address here in the Extended Version -> IP address section.

If you see the ‘datacenter’ note there, then your proxies will be immediately banned at the first need, which won’t happen when you buy the best residential and mobile proxies.

If you have any questions about proxies, which to choose or how to use them on websites, please contact our trusted team of specialists. The Astro support answers in no time.
