This is sometimes mistakenly misconfigured by network administrators, either by using other subblocks of the 192/8 network for private addresses, or by blocking the whole of 192/8 at the router.&lt;br&gt;&lt;br&gt;The three blocks of private addresses are defined in RFC 1918 - Address Allocation for Private Internets at &lt;a rel="nofollow" target="_new" href="ftp://ftp.rfc-editor.org/in-notes/rfc1918.txt"&gt;ftp://ftp.rfc-editor.org/in-notes/rfc1918.txt&lt;/a&gt;.&lt;br&gt;&lt;br&gt;The 192.1.0.0/24 network is already allocated to BBN, as you can see with a whois query (e.g. at www.dnsstuff.com).&lt;div style="clear:both;"&gt;&lt;/div&gt;&lt;img src="http://blogs.technet.com/aggbug.aspx?PostID=404166" width="1" height="1"&gt;</description></item></channel></rss>
