There are 2 32 (over four billion) IP addresses in the IPv4 protocol. Of these, almost 600 million are reserved and cannot be used for public routing. The rest are allocated to countries by the Internet Assigned Numbers Authority (IANA) via the regional Internet registries (RIRs). [1]
Starting 1991-06-01, was used to map Public Data Network addresses to IP addresses. Returned to IANA 2008-01-22. This network was reclaimed by IANA in 2007 and was subsequently re-allocated in 2010. See RFC 877 and RFC 1356 for historical information. [10] 15.0.0.0/8 ARIN: 1991-09
With the default value of 64, ranges with fewer IPv6 addresses than a /64 allocation are not considered. That means the results will not include a /n range with n > 64. |results=all Show all possible summaries, including any with a range that is too large to block (/n less than /16 for IPv4 or /19 for IPv6).
Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255 1 048 576: Private network Used for local communications within a private network [3] 192.0.0.0/24 192.0.0.0–192.0.0.255 256
