source 0.0.0.0 destination 255.255.255.255?

Hi guys,

I have a question about network.

I find there are some UDP packets being sent over my computer.
Source IP is 0.0.0.0 Destination IP is 255.255.255.255.
Source port 68 Destination port is 67

What are these packets for?

Any help or idea or hint will be appreciated !!

code

Does your ISP use DHCP for your IP?

# grep 67 /etc/services
bootpc 68/tcp dhcpc #Bootstrap Protocol Client
bootpc 68/udp dhcpc #Bootstrap Protocol Client

# grep 68 /etc/services
bootps 67/tcp dhcps #Bootstrap Protocol Server
bootps 67/udp dhcps #Bootstrap Protocol Server
