- 参数:
pool -- the range of addresses to distribute. Can be a Net, a list of IPs or a string (always gives the same IP).
network -- the subnet range
gw -- the gateway IP (can be None)
nameserver -- the DNS server IP (by default, same than gw)
domain -- the domain to advertise (can be None)

Send packets at layer 2
- 参数:
x -- the packets
inter -- time (in s) between two packets (default 0)
loop -- send packet indefinitely (default 0)
count -- number of packets to send (default None=1)
verbose -- verbose mode (default None=conf.verb)
realtime -- check that a packet was sent before sending the next one
return_packets -- return the sent packets
socket -- the socket to use (default is conf.L3socket(kargs))
iface -- the interface to send the packets on
monitor -- (not on linux) send in monitor mode

FieldRFC 3442 defines classless static routes as up to 9 bytes per entry:
# Code Len Destination 1 Router 1 +-----+---+----+-----+----+----+----+----+----+ | 121 | n | d1 | ... | dN | r1 | r2 | r3 | r4 | +-----+---+----+-----+----+----+----+----+----+
Destination first byte contains one octet describing the width followed by all the significant octets of the subnet.

- scapy.layers.dhcp.dhcp_request(hw=None, req_type='discover', server_id=None, requested_addr=None, hostname=None, iface=None, **kargs)[源代码]
Send a DHCP discover request and return the answer.
Usage:
>>> dhcp_request() # send DHCP discover >>> dhcp_request(req_type='request', ... requested_addr='10.53.4.34') # send DHCP request
