dnsmasq

One alternative caching DNS server is dnsmasq . It is avaiable for BSD and most LInux distributions , or from http://www/thekelleys.org.uk/dnsmasq/. The big advantage of fnsmasq is flexibility : it easily acts as both a caching DNS prox and an authoritative source for hosts and domains , without complicated zone file configuration . Updates can be made to zone data without even restarting the service . it can also serve as a DHC server , and wll integrate DNS service with DHCP host request . It is very lightweight , stable , and extremely flexible . Bind is likely a better choice for very large networks ( more than a couple of hundred nodes ) , bu tht esimplicity and flexibility of fnsmasq makes it attractive for small to medium sized networks .
