# flood\_dhcpc6(8)

## NAME

**flood\_dhcpc6**

## SYNOPSIS

flood\_dhcpc6 \[-n\|-N\] \[-1\] \[-d domain-name\] interface \[dhcpserver\]

DHCP client flooder. Use to deplete the IP address pool a DHCP6 server is offering. Note: if the pool is very large, this is rather senseless. :-)

By default the link-local IP MAC address is random, however this won't work in some circumstances. -n will use the real MAC, -N the real MAC and link-local address. -1 will only solicate an address but not request it. If -N is not used, you should run parasite6 in parallel. Use -d to force DNS updates, you must specify a domain name.
