Ipv6 link local address and client server application

[VikramX]

Hello Guys,
I am trying to figure out, if it is possible to have a client-server application working only with link local addresses in ipv6 network.

1) Most importantly, it is recommended?

2) Are there any limitations over such applications?

IPv6 link-local and site-local addresses are called scoped addresses. The Windows Sockets (Winsock) API supports the sin6_scope_id member in the sockaddr_in6 structure for use with scoped addresses. For IPv6 link-local addresses (fe80::/10 prefix), the sin6_scope_id member in the sockaddr_in6 structure is the interface number. For IPv6 site-local addresses (fec0::/10 prefix), the sin6_scope_id member in the sockaddr_in6 structure is a site identifier.

An example of a link-local IPv6 address on interface #5 is the following:

fe80::208:74ff:feda:625c%5
