An IP address (or Internet Protocol address) is a unique address that certain electronic devices use in order to identify and communicate with each other on a computer network using Internet protocol. It is a logical address assigned to a device in the network. Current version of IP address is Ipversion6. it is a 128 bit address. But it is not largely implemented. Current popular version in Ipv4. it is a 32 bit address. For example 61.11.124.160. IP addresses are managed and created by the Internet Assigned Numbers Authority (IANA). The IANA generally allocates super-blocks to Regional Internet Registries, who in turn allocate smaller blocks to Internet Service Providers (ISP) and enterprises.
A mask used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address. For example, consider the IP address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215) represent the Class B network address, and the second two numbers (017.009) identify a particular host on this network
Address Resolution Protocol (ARP) is a network protocol, which maps a network layer protocol address to a data link layer hardware address. For example, ARP is used to resolve IP address to the corresponding Ethernet address.
ARP belongs to the OSI data link layer (Layer 2). ARP protocol is implemented by the network protocol driver. ARP packets are encapsulated by Ethernet headers and transmitted.
RFC 826 specifies the ARP packet format and other details.
A host in an Ethernet network can communicate with another host, only if it knows the Ethernet address (MAC address) of that host. The higher level protocols like IP use a different kind of addressing scheme (like IP address) from the lower level hardware addressing scheme like MAC address. ARP is used to get the Ethernet address of a host from its IP address. ARP is extensively used by all the hosts in an Ethernet network.
The length of a MAC address is 6 bytes and the length of an IP address is 4 bytes. Obviously, the MAC address cannot be represented using the IP address. So an IP address must be mapped to the corresponding MAC address.
ARP is a general protocol, which can be used in any type of broadcast network. The fields in the ARP packet specifies the type of the MAC address and the type of the protocol address. ARP is used with most IEEE 802.x LAN media. In particular, it is also used with FDDI, Token Ring, and Fast Ethernet, in precisely the same way as it is with Ethernet.
When ARP needs to resolve a given IP address to Ethernet address, it broadcasts an ARP request packet. The ARP request packet contains the source MAC address and the source IP address and the destination IP address. Each host in the local network receives this packet. The host with the specified destination IP address, sends an ARP reply packet to the originating host with its IP address.
ARP maintains the mapping between IP address and MAC address in a table in memory called ARP cache. The entries in this table are dynamically added and removed.
The following steps results in the generation of an ARP request packet:
The IP module sends a packet, destined for another host in the network, to the ARP module.
The ARP module looks up the ARP table (cache) to resolve the IP address.
If the supplied IP address is present in the ARP cache, it is resolved into its Ethernet address.
If the ARP module is not able to find an entry for this IP address in the ARP cache, then it sends an ARP request packet to the Ethernet driver, to resolve the IP address to the Ethernet address.
After the IP address is resolved by the ARP module, the packet is sent to the Ethernet driver for transmission.
Active Directory provides a centralized control for network administration and security. Server computers configured with Active Directory are known as domain controllers. Active Directory stores all information and settings for a deployment in a central database, and allows administrators to assign policies and deploy and update software.
NetBIOS (Network Basic Input/Output System) Protocol allows applications on separate computers to communicate over a LAN. It runs over TCP/IP giving each computer in the network a NetBIOS name and IP address. E.g. It can be used for computers running Windows 2000 (or before) to join a computer network running Windows 2000 (or later).
FSMO roles are server roles in a Forest
There are five types of FSMO roles
It’s a file stored on a host machine that is used to resolve NetBIOS to specific IP addresses.
(Automatic Private IP Addressing) The Windows function that provides DHCP auto configuration addressing. APIPA assigns a class B IP address from 169.254.0.0 to 169.254.255.255 to the client when a DHCP server is either permanently or temporarily unavailable. Designed for small non-routable networks, if a DHCP server becomes available later, the APIPA address is replaced with one from the DHCP server. For example, when a Windows Vista machine starts up, it waits only six seconds to find a DHCP server before assigning an IP from the APIPA range. It then continues to look for a DHCP server. Previous versions of Windows looked for a DHCP server for up to three minutes. See DHCP auto configuration addressing, DHCP and private IP address.
Requests are on UDP port 68, Server replies on UDP 67
i)Forward Lookup Zones :-
This zone is responsible to resolve host name to ip.
ii)Reverse Lookup Zones :-
This zone is responsible to resolve ip to host name.
iii)Stub Zone :-
Stubzone is read only copy of primary zone.but it contains only 3 records the SOA for the primary zone, NS record and a Host (A) record.
Type of Record What it does
A (Host) Classic resource record. Maps hostname to IP(ipv4)
PTR Maps IP to hostname (Reverse of A (Host)
AAAA Maps hostname to ip (ipv6)
Cname Canonical name, in plain English an alias.such as
Web Server,FTP Server, Chat Server
NS Identifies DNS name servers. Important for forwarders
MX Mail servers, particularly for other domains.MX records
A domain controller (DC) or network domain controller is a Windows-based computer system that is used for storing user account data in a central database. It is the center point of the Windows Active Directory service that authenticates users, stores user account information and enforces security policy for a Windows domain.
A domain controller allows system administrators to grant or deny users access to system resources, such as printers, documents, folders, network locations, etc., via a single username and password.
Group Policy allows you to implement specific configurations for users and computers. Group Policy settings are contained in Group Policy objects (GPOs), which are linked to the following Active Directory service containers: sites, domains, or organizational units (OUs).
A Group Policy Object (GPO) is a collection of settings that control the working environment of user accounts and computer accounts. GPOs define registry-based policies, security options, software installation and maintenance options, script options, and folder redirection options.
The AD database is stored in C:WindowsNTDSNTDS.DIT.
The SYSVOL folder stores the server copy of the domain’s public files that must be shared for common access and replication throughout a domain.
All AD databases are stored in a SYSVOL folder and it’s only created in an NTFS partition. The Active Directory Database is stored in the %SYSTEM ROOT%NDTS folder.
by using the ping command we can know wether our network is dead or alive..........
Patch management is an area of systems management that involves acquiring, testing, and installing multiple patches (code changes) to an administered computer system. Patch management tasks include: maintaining current knowledge of available patches, deciding what patches are appropriate for particular systems, ensuring that patches are installed properly, testing systems after installation, and documenting all associated procedures, such as specific configurations required. A number of products are available to automate patch management tasks, including Ringmaster's Automated Patch Management, Patch Link Update, and Gibraltar's Ever guard
