AIM: To configure DNS server using cisco packet tracer

REQUIREMENT: cisco packet tracer

THEORY:

Domain Name Server (DNS) is a client server application. It is used by users (human) on
the Internet to access the domain names like gmail.com, yahoo.com, google.com etc. All
these domains can be accessed using their IP addresses. But for human beings it is
cumbersome to remember the numeric IP addresses for various sites. So the DNS servers
are configured to map the domain names (like www.xyz.com) to their IP addresses. Thus
whenever the users access any servers in the Internet, the IP addresses are provided for
their mapped domain names by the DNS. In other words, DNS translates the domain
names to IP addresses.

PROCEDURE:
Create a topology having at least one PC (you can take more than two), a router (as
default gateway, optional), and one server. One of the servers can be configured as a web
server, another as DNS etc. (At least one server is required for configuring DNS), switch
for connecting PCs in LAN)

1. Assign IP address on DNS server, start DNS services, create “A” record for its domain
name.
2. Configure the router as default gateway. This will act as the default gateway for all
PCs, DNS.
3. Configure each PC with DNS server IP server.
4. Using a web browser from each PC access the DNS server's domain name. You should
get a webpage from DNS.
5. Using command prompt from each PC run nslookup specifying the domain name of
DNS server. You should get the resolved IP address.
