IPv4 and IPv6 are versions of the Internet Protocol (IP), which is a set of rules for routing and addressing data so it can travel across networks and reach the correct destination.
IPv4 (Internet Protocol version 4):
IPv4 is the fourth version of the Internet Protocol and has been widely used since its development in the 1980s. It uses a 32-bit address scheme, which limits the number of unique addresses it can provide. This limitation led to the development of IPv6.
Example Address: 192.168.1.1
IPv6 (Internet Protocol version 6):
IPv6 is the most recent version of the Internet Protocol. It was developed to address the shortage of IP addresses available under IPv4. IPv6 uses a 128-bit address scheme, significantly increasing the number of available addresses.
Example Address: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
Nimble's Residential Proxy pool includes both IPv4 and IPv6 IPs. Because IPv4 is still the predominant IP address, there are many more IPv4 addresses available, and some websites still require them.
As such, we have enabled the option to use IPv6 addresses in addition to IPv4 addresses. Including IPv6 is set in your pipeline settings. This can be adjusted via the under a pipeline's configuration, or /v1/account/pipelines/{pipelineName} "Update a Pipeline" endpoint.
