# IP Address Filtering

Cloakify supports traffic filtering based on lists of IP addresses, IP address ranges, CIDR prefixes, and/or Autonomous System Numbers (ASNs). Each flow has two lists: a white list and a black list.

Cloakify supports both IPv4 and IPv6 addresses and CIDR notation. Here are some examples:

192.0.2.1
192.0.2.0/24
2001:db8::1
2001:db8::/112
721
AS721

Individual elements should be separated by line breaks or spaces. Please note that the system automatically merges neighboring or overlapping ranges to optimize their storage in memory and speed up searching.
