22
23       op( [BYTE] )
24           Sets/gets the BOOTP opcode.
25
26           Normal values are:
27

35
36       hlen ( [BYTE] )
37           Sets/gets the hardware address length. Value must be between 0 and
38           16.
39
40           For most NIC's, the MAC address has 6 bytes.

43           Sets/gets the number of hops.
44
45           This field is incremented by each encountered DHCP relay agent.

48           Sets/gets the 32 bits transaction id.
49
50           This field should be a random value set by the DHCP client.

54
55       flags ( [SHORT] )
56           Sets/gets the 16 bits flags.
57
58             0x8000 = Broadcast reply requested.
59
60       ciaddr ( [STRING] )
61           Sets/gets the client IP address.
62
63           IP address is only accepted as a string like '10.24.50.3'.
64
65           Note: IP address is internally stored as a 4 bytes binary string.
66           See "Special methods" below.
67
68       yiaddr ( [STRING] )
69           Sets/gets the your IP address.
70
71           IP address is only accepted as a string like '10.24.50.3'.
72
73           Note: IP address is internally stored as a 4 bytes binary string.
74           See "Special methods" below.
75
76       siaddr ( [STRING] )
77           Sets/gets the next server IP address.
78
79           IP address is only accepted as a string like '10.24.50.3'.
80
81           Note: IP address is internally stored as a 4 bytes binary string.
82           See "Special methods" below.
83
84       giaddr ( [STRING] )
85           Sets/gets the relay agent IP address.
86
87           IP address is only accepted as a string like '10.24.50.3'.
88
89           Note: IP address is internally stored as a 4 bytes binary string.
90           See "Special methods" below.
91
92       chaddr ( [STRING] )
93           Sets/gets the client hardware address. Its length is given by the
94           "hlen" attribute.
95
96           Value is formatted as an Hexadecimal string representation.
97
98             Example: "0010A706DFFF" for 6 bytes mac address.
99
100           Note : internal format is packed bytes string.  See "Special

102
103       sname ( [STRING] )

116
117       padding ( [BYTES] )
118           Sets/gets the optional padding at the end of the DHCP packet, i.e.
119           after DHCP options.
120
121           Convert to hex with:
122            unpack( 'H*', $obj->padding() )
123
124   SPECIAL METHODS
125       These methods are provided for performance tuning only. They give
126       access to internal data representation , thus avoiding unnecessary type
127       conversion.
128
129       ciaddrRaw ( [STRING])
130           Sets/gets the client IP address in packed 4 characters binary
131           strings.
132
133       yiaddrRaw ( [STRING] )
134           Sets/gets the your IP address in packed 4 characters binary
135           strings.
136
137       siaddrRaw ( [STRING] )
138           Sets/gets the next server IP address in packed 4 characters binary
139           strings.
140
141       giaddrRaw ( [STRING] )
142           Sets/gets the relay agent IP address in packed 4 characters binary
143           strings.
144
145       chaddrRaw ( [STRING] )
146           Sets/gets the client hardware address in packed binary string.  Its
147           length is given by the "hlen" attribute.
