just wondering if someone can clarify this to me? these are pings examples between 2 routers in the same network segment . why are pings successful in the first and not in the 2nd?<br />
<br />
2001:aaaa:bbbb::1/48 pings 2001:aaaa:bbbb::2/54 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= good &gt;&gt;&nbsp;why? because it shares major prefix length? arent these 2 different networks indicated by the / ? &nbsp;<br />
2001:aaaa:bbbb::1/48 pings 2001:aaaa:bbbb:400::3/54 = bad &gt;&gt;&nbsp;why? these are 2 different networks but why did the pings go through on the first?

ipv6 pings

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
