What are the valid public ip address ranges

There are a number of lists on the web that define all valid public ip addresses ranges but they don't seem to be very accurate.



The most common list Ive found is show below. This list however doesn't include addresses in 191.236.x.x even though there are public web servers in that range.



Is there a definitive and correct list?




  • 1.0.0.0 - 9.255.255.255

  • 11.0.0.0 - 126.255.255.255

  • 129.0.0.0 - 169.253.255.255

  • 169.255.0.0 - 172.15.255.255

  • 172.32.0.0 - 191.0.1.255

  • 192.0.3.0 - 192.88.98.255

  • 192.88.100.0 - 192.167.255.255

  • 192.169.0.0 - 198.17.255.255

  • 198.20.0.0 - 223.255.255.255

IANA provides standards on this subject. For IPv4, here is what they have in their "special purpose address registry". Meaning, for our purposes, anything in these address blocks shouldn't be assigned because they shouldn't be routable "publicly".



0.0.0.0/8
10.0.0.0/8
100.64.0.0/10
127.0.0.0/8
169.254.0.0/16
172.16.0.0/12
192.0.0.0/24
192.0.0.0/29
192.0.0.8/32
192.0.0.9/32
192.0.0.170/32
192.0.0.171/32
192.0.2.0/24
192.31.196.0/24
192.52.193.0/24
192.88.99.0/24
192.168.0.0/16
192.175.48.0/24
198.18.0.0/15
198.51.100.0/24
203.0.113.0/24
240.0.0.0/4
255.255.255.255/32

(Edit, also)
224.0.0.0/24
239.0.0.0/8


This is more consistent with the example you provided above.



If you don't understand CIDR notation, you can convert them to ranges here.

  • Also, there are IPv4 bogon lists which many ISPs use to block addresses from being routed on the Internet, e.g. team-cymru.org/Services/Bogons/fullbogons-ipv4.txt "A bogon prefix is a route that should never appear in the Internet routing table. A packet routed over the public Internet (not including over VPNs or other tunnels) should never have a source address in a bogon range."
    – Ron Maupin

  • Well...I guess it really boils down to whether or not you consider valid "public" ranges to be not assigned, or not reserved.

    All IP address from 1 to 191 excluding the RFC1918 private addresses below are assigned for Public IPs.:



    RFC1918 - Private address alocation:




    • 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)

      Not all of them. (100.64.0.0/10 for example?) And the public allocations don't end at 191, they continue all the way to 223.

      Thanks for the response but the point of question was to provide a reference for the valid ranges not the exclusions

    • You forgot the multicast addresses, which, from a practical perspective, cannot be used on the Internet. 224.0.0.0/4.

    • @RonMaupin That's true, thanks. I added that (as well as 239.0.0.0/8) to my post.

    • Also, there are IPv4 bogon lists which many ISPs use to block addresses from being routed on the Internet, e.g. team-cymru.org/Services/Bogons/fullbogons-ipv4.txt "A bogon prefix is a route that should never appear in the Internet routing table. A packet routed over the public Internet (not including over VPNs or other tunnels) should never have a source address in a bogon range."
