Why most local addresses are like 192.168.xxx.xxx?

Question

Is it some standard/practice or technical requirement which force network engineers to use this IP address pattern?

This is a site for *professionals*. This is such an incredibly basic question that any professional should know it. — MDMarra, Aug 30 '11 at 17:49

RFC 1918 establishes ranges for private address space.

192.168.0.0/16
172.16.0.0/12
10.0.0.0/8

There are a number of 'reserved' ranges as defined by the IETF. 192.168 is the standard used by linkysys and many other vendors for their home networking requirement. But there is no requirement for this specific subnet for home networks.
