Internet-Draft iris-areg October 2003
1. Introduction
This document describes an IRIS namespace for Internet address
registries using an XML Schema [5] derived from and using the IRIS
[9] schema. This schema and registry type are provided to
demonstrate the extensibility of the IRIS framework beyond the use of
domains, a criteria defined in CRISP [11].
The schema given is this document is specified using the Extensible
Markup Language (XML) 1.0 as described in XML [2], XML Schema
notation as described in XML_SD [4] and XML_SS [5], and XML
Namespaces as described in XML_NS [3].
Examples of client/server XML exchanges with this registry type are
available in Appendix A.

2. Document Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC2119 [8].

3. Schema Description
IRIS requires the derivation of both query and result elements by a
registry schema. These descriptions follow.
The descriptions contained within this section refer to XML elements
and attributes and their relation to the exchange of data within the
protocol. These descriptions also contain specifications outside the
scope of the formal XML syntax. Therefore, this section will use
terms defined by RFC 2119 [8] to describe the specification outside
the scope of the formal XML syntax. While reading this section,
please reference Section 4 for needed details on the formal XML
syntax.
3.1 Query Derivatives
3.1.1 <findContacts> Query
<findContacts> searches for contacts given search constraints.
The child elements <firstName>, <middleName>, and <lastName> allow
the search to be constrained against the name of the contact. These
elements may either have as children the <exactMatch> element or the
<beginsWith> and <endsWith> elements.
<eMail> constrains the query based on the e-mail address of the
contact. This may be done by an exact e-mail address using the
<exactMatch> element or by any e-mail address in a domain using the
<inDomain> element. The <inDomain> element MUST only contain a valid
domain according to RFC 1035 [1] (i.e. no '@' symbol).
3.1.2 <findOrganizations>, <findAutonomousSystems>, and <findNetworks>
The <findOrganizations>, <findAutonomousSystesm>, and <findNetworks>
elements allow for searches by name of organizations, autonomous
systems, and networks, respectively. All three have the same format.
The child element <name> may either have as children the <exactMatch>
element or the <beginsWith> and <endsWith> elements.
3.1.3 <findNetworkByAddress>
The <findNetworkByAddress> element is a query for a network given the
IP address. It contains one of these four elements:
o <ipv4Address> - contains a fully qualified IPv4 address.
o <ipv6Address> - contains a fully qualified IPv6 address. Clients
Newton Expires April 23, 2004 [Page 5]
Internet-Draft iris-areg October 2003
MUST convert any short-form notation to the fully-qualified
notation.
o <ipv4CIDR> - contains an IPv4 CIDR block address.
o <ipv6CIDR> - contains an IPv6 CIDR block address. Clients MUST
convert any short-form notation to the fully-qualified notation.
The results from this query MUST be either the <ipv4Network> result
or the <ipv6Network> result. More than one network result MAY be
returned.
3.1.4 <findSubNetworksByParent>
The <findSubNetworksByParent> element is a query to find the children
of a network, or its subnetworks, given the handle to the parent. It
has a sole child element of <networkHandle> containing the handle of
the parent network.
3.2 Result Derivatives

o <cidrAddress> contains the network address of the network in CIDR
notation form.
o <startAddress> contains the first IPv4 address of the network.
o <endAddress> contains the last IPv4 address of the network.
o <networkType> contains a string denoting the type of network.
o One or more <nameServer> elements, each containing a name, either
IP address or domain name, of a nameserver responsible for
reverse-DNS mapping for this network.
o <organization> contains an entity reference to the organization
assigned this network. The referent MUST be an <organization>
(Section 3.2.5) result.

* <parent> contains an entity reference to the parent network of
this network. The referent MUST be an <ipv4Network> (Section
3.2.1) result.
* <noParent> contains no children and simply signifies that the
network does not have a parent.
o <netContact> contains an entity references to a contact for this
network. The referent MUST be <contact> (Section 3.2.4) results.
o <registrationDate> contains the date when the network was first
registered.
o <lastUpdatedDate> contains the date when information about this
network was last updated.
o The <iris:seeAlso> element contains an entity reference specifying
an entity that is indirectly associated with this network.
3.2.2 <ipv6Network> Result
The <ipv6Network> element is a result representing an IPv6 network.
It has the following child elements:
o <ipv6NetworkHandle> contains the registry-unique assigned handle
for this network.
o <name> contains a human friendly name for the network.
o <cidrAddress> contains the network address of the network in CIDR
notation form.
o <startAddress> contains the first IPv6 address of the network.
o <endAddress> contains the last IPv6 address of the network.
o <networkType> contains a string denoting the type of network.
o One or more <nameServer> elements, each containing a name, either
IP address or domain name, of a nameserver responsible for
reverse-DNS mapping for this network.
o <organization> contains an entity reference to the organization
assigned this network. The referent MUST be an <organization>
(Section 3.2.5) result.

Internet-Draft iris-areg October 2003
o One of:
* <parent> contains an entity reference to the parent network of
this network. The referent MUST be an <ipv6Network> (Section
3.2.2) result.
* <noParent> contains no children and simply signifies that the
network does not have a parent.
o <netContact> contains an entity references to a contact for this
network. The referent MUST be <contact> (Section 3.2.4) results.
o <registrationDate> contains the date when the network was first
registered.
o <lastUpdatedDate> contains the date when information about this
network was last updated.
o The <iris:seeAlso> element contains an entity reference specifying
an entity that is indirectly associated with this network.

3.3 Support for <iris:lookupEntity>
The following types of entity classes are recognized by the
<lookupEntity> query of IRIS for this registry:
o ipv4-handle - a registry unique identifier specifying an IPv4
network. Queries with these names will yield a <ipv4Network>
result.
o ipv6-handle - a registry unique identifier specifying an IPv6
network. Queries with these names will yield a <ipv6Network>
result.
o autonomous-system - the positive integer (ASN) specifying an
autonomous system. It yields a result of <autonomousSystem>.
o as-handle - a registry unique identifier specifying an autonomous
system. It yields a result of <autonomousSystem>.
o contact-handle - a registry unique identifier of a contact.
Yields a result of <contact>.
o organization-id - a registry unique identifier of an organization.

5. BEEP Transport Compliance
IRIS allows several extensions of the core capabilities. This
section outlines those extensions allowable by IRIS-BEEP [10].
5.1 Message Pattern
This registry type uses the default message pattern as described in
IRIS-BEEP [10].
5.2 Server Authentication
This registry type uses the default server authentication method as
described in IRIS-BEEP [10].

6. URI Resolution
6.1 Application Service Label
The application service label associated with this registry type MUST
be "AREG1". This is the abbreviated form the URN for this registry
type, urn:ietf:params:xml:ns:areg1.
6.2 Bottom-Up Resolution
The bottom-up alternative resolution method MUST be identified as
'bottom' in IRIS URI's.
The process for this resolution method differs from the
direct-resolution method if the authority is only an IP address (i.e.
without the port number). The process for this condition is as
follows:
1. The IP address is converted into a domain name appropriate for
the reverse DNS tree mapping. For instance, 64.83.37.226 is
226.37.83.64.in-addr.arpa.
2. The IRIS [9] direct resolution process is tried on this
reverse-map domain name.
3. If no records are found, then the left-most component of the
reverse-map domain name is removed, and the second step is
repeated again (e.g. "37.83.64.in-addr.arpa" )
4. If all the components of the reverse-map domain name from step
one are removed and no records are found, then the original IP
address is used and the port number used is the well-known port
for the default protocol of IRIS.
6.3 Top-Down Resolution
The top-down alternative resolution method MUST be identified as
'top' in IRIS URI's.
The process for this resolution method differs from the
direct-resolution method if the authority is only an IP address (i.e.
without the port number). The process for this condition is as
follows:
1. The IP address is converted into a domain name appropriate for
the reverse DNS tree mapping. For instance, 64.83.37.226 is
226.37.83.64.in-addr.arpa.

2. The reverse-map domain name is reduced to the appropriate least
two components (e.g. "in-addr.arpa").
3. The IRIS [9] direct resolution method is tried on this
reverse-map domain name.
4. If no records are found, then the component in the original
reverse-map domain name to the right of the left-most component
of this reverse-map domain name is prepended, and the third step
is repeated (e.g. if "in-addr.arpa" then "64.in-addr.arpa", if
"64.in-addr.arpa" then "83.64.in-addr.arpa").
5. If all the components of the original reverse-map domain name
from step one are present and no records are found, then the
original IP address is used and the port number used is the
well-known port for the default protocol of IRIS.

Appendix B. Acknowledgements
Many of the concepts concerning the use of SRV records for step-wise
refinement towards finding authoritative servers and many of the
details of result objects in this draft were originally created by
Eric A. Hall in his memos regarding the use of LDAP to satisfy the
CRISP requirements. These concepts have contributed significantly to
the development of this protocol.
