Is a 192.169.0.0/16 a private address range?

Question

I know that 192.168.0.0/16 are adresses reserved for private networks. What about 192.169.0.0/16 addresses and other.. in 192.0.0.0/8. Are they routable in the "Internet" or are they also private?

Answer 1

These reserved IP-ranges for private networks are defined in RFC1918. 192.169.0.0/16 is not in them. You can verify using a WHOIS service that this /16 is divided into a number of smaller assignments to various networks.

Answer 2

No it isn't. See RFC6890 for all Special-Purpose IP Address Ranges (IPv4 and IPv6)

Answer 3

What about 192.169.0.0/16?

This is valid address space, and the addresses are routable, they are NOT private.

What about other addresses in 192.0.0.0/8?

You'd have to verify with WHOIS, some of the networks other than 192.168.0.0/16 within the 192.0.0.0/8 range are also private.

You could check anything you like in the future from just about an Linux distribution command line via the WHOIS tool:

whois 192.0.0.0/8
whois x.x.x.x/yy

Example of valid address space:

NetRange:       192.0.0.0 - 192.255.255.255
CIDR:           192.0.0.0/8

Example of private address space:

Internet Assigned Numbers Authority PRIVATE-ADDRESS-CBLK-RFC1918-IANA-RESERVED (NET-192-168-0-0-1) 192.168.0.0 - 192.168.255.255
Various Registries (Maintained by ARIN) NET192 (NET-192-0-0-0-0) 192.0.0.0 - 192.255.255.255

From RFC1918 Section 3:

   The Internet Assigned Numbers Authority (IANA) has reserved the
   following three blocks of the IP address space for private internets:

     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)

Answer 4

192.168.0.0/16 is the only private address space in 192.0.0.0/8. 192.0.0.0/24 is used by IANA, 192.0.2.0/24 is reserved for documentation and examples, and 192.88.99.0/24 is for 6to4 anycast.

Answer 5

I know that 192.168.0.0/16 are adresses reserved for private networks.

Yes

What about 192.169.0.0/16 addresses

Those are regular public IPv4 addreseses allocated to various networks.

and other.. in 192.0.0.0/8. Are they routable in the "Internet" or are they also private?

Most of the block is regular public IPs but there are a number of special things in there. Special allocations are documented at http://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml
