.SS "#define LIBNET_DONT_RESOLVE 0"
.PP
Used for libnet's name resolution functions, specifies that no DNS lookups should be performed and the IP address should be kept in numeric form.
.SS "#define LIBNET_ERRBUF_SIZE 0x100"
.PP
The libnet error buffer is 256 bytes long.
.SS "#define LIBNET_MAX_PACKET 0xffff"
.PP
The biggest an IP packet can be -- 65,535 bytes.
.SS "#define LIBNET_MAXOPTION_SIZE 0x28"
.PP
IP and TCP options can be up to 40 bytes long.
.SS "#define LIBNET_OFF 1"
.PP
Used several places, to specify 'on' or 'one'
.SS "#define LIBNET_ON 0"
.PP
Used several places, to specify 'on' or 'one'
.SS "#define LIBNET_PR2 0"
.PP
Used for \fBlibnet_get_prand()\fP to specify function disposition
.SS "#define LIBNET_RESOLVE 1"
.PP
Used for libnet's name resolution functions, specifies that a DNS lookup can be performed if needed to resolve the IP address to a canonical form.
