DHCP Server allots the IP
addresses to computers, while DNS server resolves them.
DHCP Server if you do not want to manually maintain IP Addresses or you

Server will recycle IP Addresses on machines.
DNS Server is needed
for resolving hostnames to their IP addresses. Normally your ISP will
provide you with DNS Service. You may have your own DNS Server, which will
resolve hostnames by forwarding them to ISP's DNS Server and cache the
If you have home/small office network with
Unix/Linux machines, these machines will not be resolved from each other,
as Unix/Linux machines do not support NBNS protocol and you need your own
DNS Server. But how about resolving your local machines ?. Your ISP's DNS
Server will not have this list and your own DNS Server wont have them
either. Most DNS Servers cannot do this.(unless you configure dynamic
updates, or use static IP addresses and manually enter them).
server resolves dhcp alloted local machines automatically in addition to
external hosts, with the added advantage being both dhcp and dns server
are allways in sync. Also there is no need to create and maintain
cumbersome zone files. Dual DHCP DNS Server is an Open Source Freeware. In
addition, this server is designed for Load Sharing Replicated
