Line 13: ==Example== [[Image:CIDR_Address.png\|right\|~~414px~~400px]] In the late 1990s, the IP address 208.130.29.33 (since reassigned) was used by the <tt>www.freesoft.org</tt> web server. An analysis of this address identified three CIDR prefixes. 208.128.0.0/11, a large block containing over 2 million addresses, had been assigned by [[IANA]] to [[MCI]]. Automation Research Systems, a [[Virginia]] [[Value-added reseller\|VAR]], leased an Internet connection from MCI and was assigned the 208.130.28.0/22 sub-prefix, capable of addressing just over 1000 devices. ARS used a /24 block for its public web servers, of which 208.130.29.33 was one.
