What is the 169.254.x.x IPv4 address?

Frequently Asked Questions / By

Views: 10,116The 169.254.x.x IPv4 address is called the APIPA address. APIPA stands for Automatic Private IP Addressing. It’s a fallback mechanism built into Windows (and most modern operating systems) to give your network interface a “link local” address when it can’t get one from a DHCP server. The APIPA IPv4 Addresses are any address in

Why are NAT/NPAT not a security function?

Frequently Asked Questions / By

Views: 5,093Network Address Translation (NAT) and Network Port Address Translation (NPAT) are not considered a security function because its primary purpose is to modify the L3 network address information in IPv4 packet headers and L4 port numbers of TCP or UDP while in transit. NAT and NPAT are not needed in IPv6 networking. NAT is
