HOWTO use DNS inside a home network


What is a reasonable approach to in-the-house DNS? (I literally mean, "my house.")

How do I integrate this in-house DNS with widespread use of DHCP for all of the myriad wifi devices in use -- phones, game consoles, HDTV set, tabletop internet radio, &c?

I want a caching DNS to enable file and printer services, network backup, "group ware", fax services, music and video services. We would like to use fetchmail, spamassassin &c on the server to scrub our email. Eventually we would like to use suitable proxy and other services to improve workstation protection against scum-ware.

I am self employed and have a home-office with a LAN. My professional workstations are dual-boot. I have an Ubuntu-based server and network attached storage (NAS) as well. Clients and business associates use MAC books. My family all use win-dose flavors: winXP and Vista (no 95/98/ME/NT) and the server supports SAMBA. My LAN has two access points -- one upstairs and one downstairs -- strung together with 1000baseT and "gigabit" switches. There are several network connected printers.

Thanks,

I looked at the same issue.
Trouble is, dhcp doesn't assign particular ip addresses. Sometimes you can link particular mac addresses to particular IPs in a router. If that's not a viable option, run a linux box as a server 24/7 and let it do dhcp, etc. Everything is then set up to use it as a proxy, and set IP forwarding in your server, and log in on it's own to the router. I decided to do this with different IP ranges and two nics as the most idiot proof way (e.g. 10.0.0.x inhouse & 192.168.0.x on the router). Use the setting DHCPKEEPRESOLV="yes" in the init scripts. You will then have a dhcp server on one nic, and a client on the other. You can facilitate most things like remote desktop via linux tools. I raised a middle digit to any suggestions of serving audio, or video and let people sort themselves out there.

It never went in, because I have family members who wake on a sparrow farting 500 yards away, and pc fans upset them mightily. It also has the potential to kill family contact, which is generally a bad thing, as the internet is a very dangerous friend to the vulnerable. My plan was to buy one of those via C3 m/bs. But business was just me, and we survived without it.

We each have a collection of tracks on private media and such that we already share mechanically. The idea was to make all of this available to all of us electronically, end the on-disk duplication of tracks, and archive the original physical media. In addition, with a simple in-house server, visitors can tap our family inventory and we can tap it from our phones or pda's and similar.

Cheers,
