Editing Slash (punctuation) (section)

====Networking====
The slash is used in a similar fashion in internet [[Uniform Resource Locator|URLs]] (e.g., {{mono|<nowiki>https://en.wikipedia.org/wiki/Slash_(punctuation)</nowiki>}}).<ref name="solidhart" /> Often this portion of such URLs corresponds with files on a Unix [[computer server|server]] with the same name, and this is where this convention for [[internet]] URLs comes from.

The slash in an [[IP address]] (e.g., {{mono|192.0.2.0/29}}) indicates the prefix size in [[CIDR notation]]. The number of addresses of a [[Subnetwork|subnet]] may be calculated as 2{{sup|address size − prefix size}}, in which the address size is 128 for [[IPv6]] and 32 for [[IPv4]]. For example, in IPv4, the prefix size/29 gives: 2{{sup|32–29}} = 2{{sup|3}} = 8 addresses.
