LAN DHCP Use a DHCP server in your

network to assign dynamic IP

addresses to each device.

Most routers and switches

have DHCP servers integrated.

If yours doesn’t have, you can

use the DHCP server in a Linux

machine (dhcpd).

Assign dynamic IP to clients

For large networks you should

have DHCP redundancy. If you

have lots of guests, you can

decrease the lease time.

LAN : DNS Unlessyouhave<5devices

(machines, Switches, routers,

AP’s ….) on your network,

you will need internal DNS to

resolve machine names.

Most DHCP server also

have a DNS server making

resolving static and dynamic

IP’s on your internal network

For External name resolution

(e.g. www.google.com) you

should use your ISP DNS or

Googles public DNS as per

this doc

Where possible you should

have multiple (redundant)

DNS servers to prevent name

resolution problems that can

make it seem like your whole

network is down to your users
