QR A one bit field that specifies whether this message is a query (0), or a response (1). For example, SOA records are always distributed with a zero TTL to prohibit caching. This identifier is copied the corresponding reply and can be used by the requester to match up replies to outstanding queries. Zero values are interpreted to mean that the RR can only be used for the transaction in progress, and should not be cached. The header contains the following fields: 1 1 1 1 1 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- | ID | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- |QR| Opcode |AA|TC|RD|RA| Z | RCODE | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- | QDCOUNT | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- | ANCOUNT | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- | NSCOUNT | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- | ARCOUNT | -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- where: ID A 16 bit identifier assigned by the program that generates any kind of query.

Although labels can contain any 8 bit values in octets that make up a label, it is strongly recommended that labels follow the preferred syntax described elsewhere in this memo, which is compatible with existing host naming conventions. Thus a program which wanted to locate gateways on net 10 would originate a query of the form QTYPE=PTR, QCLASS=IN, QNAME=10. The names of the sections after the header are derived from their use in standard queries. To simplify implementations, the total length of a domain name (i.e., label octets and label length octets) is restricted to 255 octets or less. The header includes fields that specify which of the remaining sections are present, and also specify whether the message is a query or a response, a standard query or some other opcode, etc. The high order two bits of every length octet must be zero, and the remaining six bits of the length field limit the label to 63 octets or less. The top level format of message is divided into 5 sections (some of which are empty in certain cases) shown below: --------------------- | Header | --------------------- | Question | the question for the name server --------------------- | Answer | RRs answering the question --------------------- | Authority | RRs pointing toward an authority --------------------- | Additional | RRs holding additional information --------------------- The header section is always present.

The basic rule is that case can be discarded only when data is used to define structure in a database, and two names are identical when compared in a case insensitive manner. labels 63 octets or less names 255 octets or less TTL positive values of a signed 32 bit number. This policy avoids problems with caching multiple types and defining QTYPEs to match multiple types. Y, they are actually stored at the same place in the database, and hence only one casing would be preserved. Y may both be stored under a single location x.y or X. Various objects and parameters in the DNS have size limits. Some could be easily changed, others are more fundamental. In defining a new type of data, multiple RR types should not be used to create an ordering between entries or express different formats for equivalent bindings, instead this information should be carried in the body of the RR and a single type used. When data enters the domain system, its original case should be preserved whenever possible. For example, if two RRs are stored in a database, one at x.y and one at X. The data distribution system in the domain system will ensure that consistent representations are preserved. This approach is preferred because it avoids the opportunity for inconsistency. Forex what is margin level. However, future additions beyond current usage may need to use the full binary octet capabilities in names, so attempts to store domain names in 7-bit ASCII or use of special bytes to terminate labels, etc., should be avoided. Systems administrators who enter data into the domain database should take care to represent the data they supply to the domain system in a case-consistent manner if their system is case-sensitive. Thus, in order to find the address of the host for a mail exchange, you map the mail domain name to a host name, then the host name to addresses, rather than a direct mapping to host address. At present, this rule is in force throughout the domain system without exception. In general, this preserves the case of the first label of a domain name, but forces standardization of interior node labels. The present system attempts to minimize the duplication of data in the database in order to insure consistency. For all parts of the DNS that are part of the official protocol, all comparisons between character strings (e.g., labels, domain names, etc.) are done in a case-insensitive manner. The multiple RRs assumption is incorporated in some experimental work on dynamic update methods.
The structure of the domain data and the necessity for synchronization between name servers and resolvers imply the general characteristics of this database, but the actual format is up to the local implementor. The contents of the shared database will typically be a mixture of authoritative data maintained by the periodic refresh operations of the name server and cached data from previous resolver requests. The information flow in a host that supports all aspects of the domain name system is shown below: Local Host | Foreign | --------- ---------- | -------- | | user queries | |queries | | | | User |--------------| | | queries | |Foreign | | | | Name | ------------------|--| Server | maintenance responses | -------- The shared database holds domain space data for the local name server and resolver. Handel gmbh. That is, two names with the same spelling but different case are to be treated as if identical. That is, the bit labeled 0 is the most significant bit. New types and classes need mnemonics for master files; the format of the master files requires that the mnemonics for type and class be disjoint. ::= any one of the ten digits 0 through 9 Note that while upper and lower case letters are allowed in domain names, no significance is attached to the case. 0 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 - - - - - - - - - - - - - - - - | 1 | 2 | - - - - - - - - - - - - - - - - | 3 | 4 | - - - - - - - - - - - - - - - - | 5 | 6 | - - - - - - - - - - - - - - - - Whenever an octet represents a numeric quantity, the left most bit in the diagram is the high order or most significant bit. New classes are appropriate when the DNS is to be used for a new protocol, etc which requires new class-specific data formats, or when a copy of the existing name space is desired, but a separate management domain is necessary. The following syntax will result in fewer problems with many applications that use domain names (e.g., mail, TELNET). For example, in the following diagram, the octets are transmitted in the order they are numbered. Designers should attempt to define types and their RDATA formats that are generally applicable to all classes, and which avoid duplication of information.

This can be appropriate for PCs or hosts which want to minimize the amount of new network code which is required. Sometimes this is done to offload less capable hosts so that they do not have to implement a full resolver. Information flow can also be tailored so that a group of hosts act together to optimize activities. Auto broker denver co. Defining new types, classes, and special namespaces 24 4. The idea is that the name of any existing object can be expressed as a domain name with minimal changes. - Systems that use the domain database to initialize their routing tables must start with enough gateway information to guarantee that they can access the appropriate name server. The DNS specifications attempt to be as general as possible in the rules for constructing domain names. - Gateways will often have two names in separate domains, only one of which can be primary. While the implementor is free to violate these conventions WITHIN HIS OWN SYSTEM, he must observe these conventions in ALL behavior observed from other hosts. ARPA special domain and the normal domain for a particular host or gateway will be in different zones, the possibility exists that that the data may be inconsistent.
