An Internet address can be an IPv4
4、address, an IPv6 address or a DNS domain name.REVISION 200006080000ZDESCRIPTION Initial version, published as RFC 2851.:= mib-2 76 InetAddressType := TEXTUAL-CONVENTION STATUS current DESCRIPTION A value that represents a type of Internet address. unknown(0) An unknown address type. This value MUST
5、be used if the value of the corresponding InetAddress object is a zero-length string. It may also be used to indicate an IP address which is not in one of the formats defined below. ipv4(1) An IPv4 address as defined by the InetAddressIPv4 textual convention. ipv6(2) An IPv6 address as defined by th
6、e InetAddressIPv6 textual convention. dns(16) A DNS domain name as defined by the InetAddressDNS textual convention. Each definition of a concrete InetAddressType value must be accompanied by a definition of a textual convention for use with that InetAddressType. The InetAddressType textual conventi
7、on SHOULD NOT be subtyped in object type definitions to support future extensions. It MAY be subtyped in compliance statements in order to require only a subset of these address types for a compliant implementation. SYNTAX INTEGER unknown(0), ipv4(1), - these named numbers are aligned ipv6(2), - wit
8、h AddressFamilyNumbers from dns(16) - IANA-ADDRESS-FAMILY-NUMBERS-MIB InetAddress := TEXTUAL-CONVENTION STATUS current DESCRIPTION Denotes a generic Internet address. An InetAddress value is always interpreted within the context of an InetAddressType value. The InetAddressType object which defines t
9、he context must be registered immediately before the object which uses the InetAddress textual convention. In other words, the object identifiers for the InetAddressType object and the InetAddress object MUST have the same length and the last sub-identifier of the InetAddressType object MUST be 1 le
10、ss than the last sub-identifier of the InetAddress object. When this textual convention is used as the syntax of an index object, there may be issues with the limit of 128 sub-identifiers specified in SMIv2, STD 58. In this case, the OBJECT-TYPE declaration MUST include a SIZE clause to limit the nu
11、mber of potential instance sub-identifiers. SYNTAX OCTET STRING (SIZE (0.255)InetAddressIPv4 := TEXTUAL-CONVENTION DISPLAY-HINT 1d.1d.1d.1d STATUS current DESCRIPTION Represents an IPv4 network address: octets contents encoding 1-4 IP address network-byte order The corresponding InetAddressType valu
12、e is ipv4(1). SYNTAX OCTET STRING (SIZE (4)InetAddressIPv6 := TEXTUAL-CONVENTION DISPLAY-HINT 2x:2x:2x:2x:2x:2x:2x:2x%4d STATUS current DESCRIPTION Represents an IPv6 network address: octets contents encoding 1-16 IPv6 address network-byte order 17-20 scope identifier network-byte order The correspo
13、nding InetAddressType value is ipv6(2). The scope identifier (bytes 17-20) MUST NOT be present for global IPv6 addresses. For non-global IPv6 addresses (e.g. link-local or site-local addresses), the scope identifier MUST always be present. It contains a link identifier for link-local and a site iden
14、tifier for site-local IPv6 addresses. The scope identifier MUST disambiguate identical address values. For link-local addresses, the scope identifier will typically be the interface index (ifIndex as defined in the IF-MIB, RFC 2233) of the interface on which the address is configured. The scope iden
15、tifier may contain the special value 0 which refers to the default scope. The default scope may be used in cases where the valid scope identifier is not known (e.g., a management application needs to write a site-local InetAddressIPv6 address without knowing the site identifier value). The default s
16、cope SHOULD NOT be used as an easy way out in cases where the scope identifier for a non-global IPv6 is known. SYNTAX OCTET STRING (SIZE (16|20)InetAddressDNS := TEXTUAL-CONVENTION DISPLAY-HINT 255a STATUS current DESCRIPTION Represents a DNS domain name. The name SHOULD be fully qualified whenever possible. The corresponding InetAddressType is dns(16). The DESCRIPTION clause of InetAddress objects that may have InetAddressDNS values must fully describe how (and when) such names are to be resolved to IP addresses. SYNTAX OCTET STRING (SIZE (1.255)END
