Want to verify my answers and see if im correct and if im not what should it be.

"set up a network of publicly available services on that network. Please read the rest of the instructions and answer carefully, the answer boxes will be doing string matches, to the best of your ability. You will get three submissions chances to get it right.

They have bought the public IP subnet of 192.165.1.192/26 to be used. You need to divide that subnet into three subnets. One for infrastructure that can support 14 nodes, one for public services that can support 30 nodes, and one for private services that can support 14 nodes. The lowest numeric value IPs should be used for the private services.

They will need you to configure a ISC DHCP server that will hand out the last half of each subnets IPs except the last usable IP (that will be used as the default-gateway. The DHCP server will also be the Name Server (DNS Server) (named net-srv.infra.165pro.net) for the three subnets as well. The IP of the DHCP and DNS server is the first usable IP of the infrastructure subnet. The default and max lease time should be set to one week. The domain names for the three subnets should be set to infra.165pro.net, prv.165pro.net, and pub.165pro.net.

Please provide in the text box below the three subnets from lowest value network address to highest in the following format:

Example:

X.X.X.X/XX

X.X.X.X/XX

X.X.X.X/XX

Answer:

192.165.1.192/28

192.165.1.208/27

192.165.1.224/28

Next provide usable configuration for the ISC DHCP to set the default and max lease times to one week in the following format:

Example:

default-lease-time X;

max-lease-time X;

Answer:

default-lease-time ; 604800

max-lease-time ; 604800

Then the configuration of the dhcpd.conf file for the three subnets. Be sure to set the default gateway, dns server, and domain names of the subnets. Also they must be, for this submission, be in the following order no matter the value IP addresses: infrastructure, public and then private. Be sure to get the syntax correct (there will be a string match for the grade) following the example:

Example:

# Infrastructure Subnet

subnet X.X.X.X netmask X.X.X.X {

range X.X.X.X X.X.X.X;

option routers X.X.X.X;

option domain-name-servers X.X.X.X;

option domain-name "x";

}

# Public Subnet

subnet X.X.X.X netmask X.X.X.X {

range X.X.X.X X.X.X.X;

option routers X.X.X.X;

option domain-name-servers X.X.X.X;

option domain-name "x";

}

# Private Subnet

subnet X.X.X.X netmask X.X.X.X {

range X.X.X.X X.X.X.X;

option routers X.X.X.X;

option domain-name-servers X.X.X.X;

option domain-name "x";

}

Answer:

# Infrastructure Subnet

subnet 192.165.1.192 netmask 255.255.255.240{

range 192.165.1.193 192.165.1.206;

option routers 192.165.1.206;

option domain-name-servers 192.165.1.193 ;

option domain-name "infra.165pro.net";

}

# Public Subnet

subnet 192.165.1.208 netmask 255.255.255.224{

range 192.165.1.209 192.165.1.238;

option routers 192.165.1.238;

option domain-name-servers 192.165.1.193;

option domain-name "pub.165pro.net";

}

# Private Subnet

subnet 192.165.1.224 netmask 255.255.255.240{

range 192.165.1.225 192.165.1.238;

option routers 192.165.1.238;

option domain-name-servers 192.165.1.193;

option domain-name "prv.165pro.net";

}

Next set a static reservation for the web server with the computer name www that will be the first usable address on the public subnet and provide the config for that server (including comments) in the following format

Example:

# www.165pro.net Web Server Static Reservation

host x

{

hardware ethernet 00:1F:51:33:A2:E8;

fixed-address X.X.X.X;

}

Answer:

# www.165pro.net Web Server Static Reservation

host www

{

hardware ethernet 00:1F:51:33:A2:E8;

fixed-address 192.165.1.209 ;

}

They also need you to help with the setup of the DNS server as well. Please provide the A record in the infra.165pro.net for the DHCP and DNS server (named net-srv.infra.165pro.net) located in the db.165pro.net file with the following format:

Example:

net-srv IN x X.X.X.X

Answer:

net-srv IN A 192.165.1.193

Finally give the configuration for the reverse lookup zones file to be added in the /etc/bind/named.conf.local file in the following format:

Example(of note lowercase xs are alphabetic and uppercase Xs are numeric):

zone X.X.X.x.x {

type master;

file /etc/bind/x.X.X.X;

};

Answer:

zone 1.165.192.in-addr.arpa {

type master;

file /etc/bind/db.1.165.192;

};"
