subnettools ipinfo 'subnet' can give the following informations about 'subnet'
- network address, last subnet address
- known prefix membership (IPv6 global addresses, RFC 1918 private subnet, multicast, etc...)
Decoding of following addresses :
- Teredo
- IPv6 multicast (including embedded RP)
- 6to4
- ISATAP link-local address
- IPv4 glop
- rfc 6052
- EUI-64 Interface ID

example :
[etienne@ARODEF subnet_tools]$ ./subnet-tools ipinfo FF72:340:2001:DB8:BEEF:FEED::32
IP version : 6
Network Address : ff72:340:2001:db8:beef:feed:0:32/128
Address   Range : ff72:340:2001:db8:beef:feed:0:32 - ff72:340:2001:db8:beef:feed:0:32
Previous subnet : ff72:340:2001:db8:beef:feed:0:31/128
Next     subnet : ff72:340:2001:db8:beef:feed:0:33/128
IPv6 multicast address
Scope : Link Local
Flags : 7
R=1, Embedded RP
P=1, based on network prefix
T=1, dynamically assigned prefix
Embedded RP Address : 2001:db8:beef:feed::3

[MAJOR] rename st_vscanf to sto_sscanf that takes sto table as argument
make st_sprint just call that and restore 'ap'
sto_sscanf in itself maybe verrry interesting to use
