| The range of IP addresses (from 169.254.0.1 through 169.254.255.254) used for APIPA is reserved by the Internet Assigned Numbers Authority (IANA). Any IP addresses within this range are not used on the Internet.
Is it still called private IP address? what's the difference of this range and other private IP address ranges like 10.0.0.0-10.255.255.255 etc?
Thanks a lot! | |

Nope. Only 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 are called "private networks" or "private internets". I guess the difference is in the purpose of 169.254.0.0/16: link local, failover for DHCP, blah blah blah... | |

| as dmaftei says you'll notice you get an address from that range if you fail to get a dhcp address. Some mistakenly say that is because Microsoft owns that range.

| Well APIPA is exclusively a Microsoft feature if I'm not mistaken. You won't find 169.254.*.* when your computer fails to find a DHCP lease while in linux, freebsd, solaris, etc. The difference is that this range isn't defined in the 1918 rfc because it's just a public address block owned by the IANA and obviously they will never work because they are not comming from your ISP's pool of addresses. | |

I read somewhere that some MACs can also do APIPA. Any MAC user around here could confirm? | |
