DHCP client: dhclient vs dhcpcd ?

[KIRIHARA Masaharu <mki_open%yahoo.co.jp@localhost>]

Hello,

NetBSD has two DHCP clients; dhclient(8) and dhcpcd(8).
What's the difference?
Which is better to use?

In https://www.netbsd.org/docs/network/dhcp.html ,
dhclient is appeared.

In https://www.netbsd.org/docs/guide/en/chap-net-practice.html ,
dhcpcd is appeared.

I'm confused...


Thanks,
