A

ASN

Autonomous System Number network
A unique identifier for a network on the internet (e.g. AS16509 for Amazon AWS, AS6939 for Hurricane Electric). Anti-bot systems look at the ASN of an IP: if it belongs to a data centre, that's a bot signal. Residential ASNs (Comcast, Vodafone, BT) look natural.

D

Datacenter proxy

type
Proxies with IPs from server centres (AWS, Hetzner, OVH). Cheapest ($0.5-2/GB) and fastest, but easily detected by anti-bot systems via the ASN.
See also: asn residential

F

Floating IP

technical
An IP that changes automatically within a defined range (usually within a single ASN). Less stable than dedicated, but more stable than rotating.
See also: rotation sticky-session

G

Geo-targeting

feature
The ability to choose the country/city for the exit IP. Minimum precision: country (every provider). Mid: city, ASN (top 10). Maximum: ZIP code (Bright Data, GeoSurf).
