Planning and Implementing a DNS Namespace

Last edited by . Total of no comments in the discussion.

Host Name Resolution Overview In networks running the TCP/IP protocol suite, IP address information is used to forward packet to the destination computer. The packets that are transmitted over the network contain the IP address of the computer sending the packet; and the IP address of the destination computer intended to receive the packet. The IP addresses of computers therefore have to be both unique and correct so that they can be forwarded to the correct destination. IP addresses contain the network address and the host address. A host name Read More

DNS Queries Overview The naming system used by DNS is a hierarchical namespace, called the DNS namespace. The DNS namespace has a unique root. The root can contain numerous subdomains. Each subdomain also can contain multiple subdomains. Each domain registered in DNS is connected to a DNS name server. The DNS server of a domain provides authoritative replies to queries for that particular domain. The DNS server manages the DNS database that resides on it. DNS server is authoritative for the contiguous portion of the DNS namespace over which it Read More

DNS Zones Overview A DNS zone is the contiguous portion of the DNS domain name space over which a DNS server has authority. A zone is a portion of a namespace. It is not a domain. A domain is a branch of the DNS namespace. A DNS zone can contain one or more contiguous domains. A DNS server can be authoritative for multiple DNS zones. A non-contiguous namespace cannot be a DNS zone. A zone contains the resource records for all of the names within the particular zone. Zone files Read More

Securing DNS Servers

Last edited by . Total of no comments in the discussion.

Domain Name System (DNS) is the primary name registration and resolution service used in Windows Server 2003. DNS provides a hierarchically distributed and scalable database; provides name registration and name resolution services, and service location for Windows 2000 and Windows Server 2003 clients; and locates domain controllers for logon. A DNS server is a computer running the DNS Server service that provides these domain name services. The common threats to DNS servers are: Denial-of-service (DoS) attacksoccur when DNS servers are flooded with recursive queries in an attempt to prevent the Read More
