Chapter 6.6 IP Configuration
It can deliver a DNS server address in addition to the host IP address.
DHCP servers deliver IP addresses as well as other host configuration information to network hosts. DHCP can be configured to assign any available address to a host, or it can assign a specific address to a specific host. DCHP clients, typically workstations, must send a request to a DCHP server before it will send IP addressing information to them.
The DHCP protocol allows you to assign IP addresses automatically. In this scenario, you should configure the DHCP service to rin on the network server. The DHCP client on each workstation can then contact the DHCP server when the workstations connect to the network to be automatically assigned IP addressing information. You could instruct each user to manually enter IP addressing information but there is a higher change of error and will likely require more administrative overhead.
The default gateway identifies the router to which packets for remote networks are sent. The subnet mask identifies which portion of the IP address is the network address. The WINS server address identifies the WINS server that is used to resolve NetBIOS host names to IP addresses. The DNS server address identifies the DNS server that is used to resolve host names to IP Addresses. The alternate IP address identifies IP addressing information to be ised in the event the DHCP server can’t be reached. The host name identifies the logical name of the local system.
Use the Network and Sharing Center in Windows Vista/7 to view and manage network connections. My Network Places is in Windows XP, and Network Neighborhood is in Windows 98. Use Internet Options to configure Internet and Internet Explorer settings.
You can use the Dynamic Host Configuration Protocol (DHCP) to set up a DHCP server that will assign IP addresses automatically to network hosts. DHCP servers will not assign the same IP address to two different hosts. ICMP is chiefly used by networked computers’ operating systems to send error messages. The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite. The Internet Group Management Protocol (IGMP) is a communications protocol used to manage the membership of Internet Protocol multicast groups
You can use the Domain Name System (DNS) to get the IP address from a given host name. You can also use the local hosts file to map host names into IP addresses. On Windows systems, the file is located in C:Windowssystem32driversetc. You can use either the DHCP protocol or the BOOTP protocol to assign IP address and other configuration information to hosts automatically. Use FTP to transfer files.
After doing so, most users are able to accress the shares on the spare server by host name, but serveral users cannot. Instead, they see and error message indication the FS1 server could not be found.
Enter the command yo can run from the command prompt on these workstations that will allow them to access the shares on FS1 without performing a full restart.
Workstation maintain a cache of recently-resolved DNS names. When you use a DNS name, the computer first checks its cache. If the name is in the cache, the corresponding IP address will b used. This can sometimes cause problems if the IP address of a host has changed/ Old values in the cache might continue to be used for a time making communication using the DNS name impossible. To correct this problem on a Windows computer, run ipconfig /flushdns to delete the local DNS name cache
-IP address: 169.254.0.1
-Subnet mask: 255.255.0.0
-Automatic Private IP Addressing (APIPA).
Why did the workstation receive this type of configuration?
-The workstation was unable to contact the DHCP server.
If a Windows client is configured to receive an IP address from a DHCP server, but cannot contact a DHCP server, it will automatically assign itself an IP address within the range of 169.254.0.1 to 169.254.255.254 with the subnet mask of 255.255.0.0 You can use APIPA instead of a DHCP server, but it should only be used on a small network that does not need a default gateway or DNS server setting configured.
With static IP addressing, you manually assign all configuration values. Static addressing is prone to error and should only be used under the following conditions:
-The network has a small number of hosts.
-The network will not change or grow.
-You have hosts that must always use the same IP address.
Which IP addressing method can you use to make sure he gets a network connection at home?
With an Alternate IP Configuration, the systems’s IPv4 Properties are configured on the General tab to use DHCP to automatically obtain TCP/IP configuration information. If a DHCP server cannot be contacted, the static IP configuration information on the IPv4 Properties’ Alternate Configuration tab is used.
