I want to send a messaged from Windows/Linux to a IPV6 virtual IP address which I had created on Ubuntu. Can anyone suggest the process to do so?

I created Virtual IPV6 in Ubuntu by the following Code: sudo ip -6 addr add 2002:1:1:1::10/64 dev eth0

And, for sending a message to IPV6 I used this Pyhton Code:

For Client:

# Echo client program
import socket
import sys

HOST = '2002:1:1:1::10'       # The remote host
PORT = 50007              # The same port as used by the server
s = None
for res in socket.getaddrinfo(HOST, PORT, socket.AF_UNSPEC, socket.SOCK_STREAM):
    af, socktype, proto, canonname, sa = res
    try:
        s = socket.socket(af, socktype, proto)
    except OSError as msg:
        s = None
        continue
    try:
        s.connect(sa)
    except OSError as msg:
        s.close()
        s = None
        continue
    break
if s is None:
    print('could not open socket')
    sys.exit(1)
s.sendall(b'Hello, world')
data = s.recv(1024)
s.close()
print('Received', repr(data))

For Server:

# Echo server program
import socket
import sys

HOST = '2002:1:1:1::10'               # Symbolic name meaning all available interfaces
PORT = 50007              # Arbitrary non-privileged port
s = None
for res in socket.getaddrinfo(HOST, PORT, socket.AF_UNSPEC,socket.SOCK_STREAM, 0, socket.AI_PASSIVE):
    af, socktype, proto, canonname, sa = res
    # The AF_* and SOCK_* constants are now AddressFamily and SocketKind IntEnum collections.
    try:
        s = socket.socket(af, socktype, proto)
    except OSError as msg:
        s = None
        continue
    try:
        s.bind(sa)
        s.listen(1)
    except OSError as msg:
        s.close()
        s = None
        continue
    break
if s is None:
    print('could not open socket')
    sys.exit(1)
conn, addr = s.accept()
print('Connected by', addr)
while True:
  data = conn.recv(1024)
  print(data)
  if not data: break
  conn.send(data) 
conn.close()

When I run this program I receive this error: [Errno 101] Network is unreachable. And, I cant ping the virtual IPV6.

IPv6 地址以2002:6to4 地址开头。关于如何使用和路由这些有特殊规则。您使用的地址链接到 IPv4 地址0.1.0.1，这不是有效的 IPv4 地址，因此您的 IPv6 地址也是无效的。

使用 IPv6 时，您应该使用 ISP 提供的官方地址。如果您无法从您的 ISP 获得地址，并且只希望地址供本地使用，请使用 ULA 地址。你可以自己生成这些。有多个网站都有您可以使用的在线生成器。
