Will IP address run out?

The Internet is running out of room. Experts predict that in two or three years we will run out of Web addresses, so-called IP addresses, that can be assigned to new Internet-based sites and services. Each site is assigned a unique number based on the IPv4 standard.

What is a 255.255 255.0 subnet?

A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.

What does 192.168 mean?

1.1 – Computer Definition. The common default IP address of a router. Although it can be changed to another private IP addressing space, most of the time, the 192.168 range is used, and the default router address is left as is. See private IP address.

Did we run out of IPv4 addresses?

Yes, this news may sound familiar. WIRED reported back in 2011 that the Internet had run out of IP addresses, or more specifically, that an organization called Internet Assigned Numbers Authority (IANA) had run out of IPv4 addresses. … So even after IANA ran out, many IPv4 addressees were still available.
