IPv4 address allotments have run out everywhere except for Africa. With global IP addresses at their limit, service providers need to make the shift to IPv6. BIG-IP Carrier-Grade NAT (CGNAT) supports both IPv6 and IPv4 addresses, without costly hardware upgrades. IPv4 packets are encapsulated in an IPv6 tunnel and sent to an external IPv4 destination.
BIG-IP CGNAT supports iPFIX to compress NAT logging, leading to high-speed logging capabilities. It reduces the amount of data per log entry, minimizing overall costs. BIG-IP CGNAT also enables high-speed log generation of individual security events.
NAT functionality includes:
• NAT44 to extend the use of IPv4 addresses.
• NAT 64 to allow IPv6 endpoints to access IPv4 content and destinations.
• DNS64 which uses DNS AAAA records so IPv4 addresses can be seen as IPv6.
