ipv4 compatible with ipv6

["Luis" <itachi@cnt.uo.edu.cu>]

hey there
i have some questions

well lets start

i have external ipv4 network and internal ipv6 network
no how can i access to ipv4 network from ipv6 network ?

is there a way

i was googling and some people talk about ipv6 compatible with 4??



example

10.30.143.1 would be reachable from ipv6 as ::ffff:10.30.143.1 rigth

now check this
itachi@server6:~$ ping6 ::ffff:10.30.143.1
PING ::ffff:10.30.143.1(::ffff:10.30.143.1) 56 data bytes
ping: sendmsg: Network is unreachable
ping: sendmsg: Network is unreachable

--- ::ffff:10.30.143.1 ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1012ms

may i add that the ip 10.30.143.1 is local ipv4 address

eth0      Link encap:Ethernet  HWaddr 00:01:80:09:6A:3F
          inet addr:10.30.143.1  Bcast:10.30.143.255  Mask:255.255.255.0
          inet6 addr: fe80::201:80ff:fe09:6a3f/64 Scope:Link
          inet6 addr: 2001:b00:f80e:6c00::1/64 Scope:Global

now what i have to do here?

i would like to bring more services in my network using ipv6 , any ideas ??

regards
.
