Implementing Name Resolution tutorials

  • Now let’s learn how a name can be an alternative to an IP address when identifying computer on a network.

  • Name resolution is important aspect of computer networking because it is easier for users to remember names than IPv4 address.

  • When you access LAN or WAN, Intranet or Internet website, we use any of following format with browser, Command Prompt or Window based program.

For example

\\computer_name\share_name

http: //173.194.36.17

\\ 192.168.10.5

\\ 192.168.10.5\share_name

File: //192.168.10.2/share_name

  •  

  • If an application request network services through Windows Sockets or Winsock Kernel, it uses Host Name.

  • If application request services through NetBIOS, it uses NetBIOS name.

 

There are two types of computer name

NetBIOS Name

Host Name

The NetBIOS name is 16 characters, however Microsoft limits it to 15 character long computer name and 16th character identifies service.

A Host name is a user friendly name associated with IP address. Host name can go up to 255 characters in length, can contain Alphabet, Numeric, Period and Hyphens.

Flat name space

It is alias or FQDN (Fully Qualified Domain Name)

Windows support a number of methods for resolving computer name such as DNS, WINS and host name resolution process.

An alias is a single name associated with an IP address.

The host name combines an alias with domain name to create the FQDN

For example CBTSAM

For example www.cbtsam.com

 

Name Resolution with WINS

  • WINS (Windows Internet Name Service) is Microsoft’s implementation of NetBIOS name service.

  • Old Version of Microsoft Operating System such as Windows Server 2003 rely on WINS for name resolution

  • Some typically older applications rely on NetBIOS names.

  • User rely on the Network Neighbourhood or My Network Places network browser features for Windows 98 and Windows XP.

 

Name Resolution with DNS

  • Used with Windows Server 2003 onward.

  • The DNS is the Microsoft standard for resolving host names to IP Addresses.

  • When an application specifies a host name and uses Windows Sockets, TCP/IP uses the DNS resolver cache, DNS and LLMNR (Link-Local Multicast Name Resolution) to resolve the host name to IP Addresses.

 

LLMNR sequence

  • Search Local Subnet

  • Converting host name to NetBIOS name and check the Local NetBIOS name cache

  • Send DNS request to configured WINS server

  • Broadcast Three NetBIOS name Query request on subnet that are directly attached

  • Search the LMHOST file.

GNZ (Global Name Zone)

  • GNZ is feature of Windows Server 2008.

  • GNZ provides single-label name resolution for large enterprise that do not deploy WINS.

  • GNZ is manually created and not available for dynamic registration of record.

  • GNZ is used to assist the migration from WINS. However it is not replacement for WINS.

  • Instead of using GNZ, you can configure DNS and WINS integration.
