isc::asiolink::IOAddress addr_
contains an IPv6 address
Class that represents IAPREFIX option in DHCPv6.
static const size_t OPTION6_IAPREFIX_LEN
length of the fixed part of the IAPREFIX option
virtual std::string toText(int indent=0) const
Returns string representation of the option.
virtual void unpack(OptionBufferConstIter begin, OptionBufferConstIter end)
Parses received buffer.
void setPrefix(const isc::asiolink::IOAddress &prefix, uint8_t length)
sets address in this option.
virtual OptionPtr clone() const
Copies this option and returns a pointer to the copy.
virtual uint16_t len() const
returns data length (data length + DHCPv4/DHCPv6 option header)
void pack(isc::util::OutputBuffer &buf, bool check=true) const
Writes option in wire-format.
virtual bool valid() const
returns if option is valid (e.g.
