Ipv6 addresses can be written in several different formats. The "::ffff" part is equivalent to :0:0:0:0:ffff. Further info: http://en.wikipedia.org/wiki/IPv4_mapped_address ] As a special exception to IPv6 addresses notation, IPv4 mapped addresses ] are commonly represented with their last 32 bits notated as an IPv4 ] address. As such, ::ffff:c000:280 would typically be notated ] ::ffff:192.0.2.128 instead. And rfc4291. More proofs: [EMAIL PROTECTED]:~> host ::ffff:195.135.221.135 Host 7.8.d.d.7.8.3.c.f.f.f.f.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa not found: 3(NXDOMAIN) See? The host command knows how to read and interpret it, so it is standard notation. - -- Cheers, Carlos E.
