VitalQIP software performs a complete generation of all named.conf and zone data files. Alcatel-
Lucent Technologies will implement an incremental primary update in which only changes within the
database will be updated to zone files. Incremental Zone Transfers (IXFRs) are supported by Alcatel-
Lucent as an extension to BIND 8.x.
Once the configuration files and zone data files are generated there is no further communication
required to the Enterprise database server. The DNS servers operate independently of the database
and perform based on the DNS standards.
In the event a remote DNS server operates on an operating system not currently supported, VitalQIP
software provides a mechanism in which DNS configuration files can be generated locally. Using the
software‟s DNS user-exit, the files can then be transferred to the remote server (via ftp, rcp, or srcp).
Dynamic DNS
VitalQIP software provides two (2) methods for dynamic DNS updates:
Static addresses
Dynamic addresses via DHCP
If enabled, all static address assignments, performed through one of the user interfaces, can be
dynamically updated to primary and secondary DNS servers. Alcatel-Lucent provides the additional
functionality to secondary DNS servers so corporations could point a client‟s primary resolver to the
dynamically updated secondary DNS server instead of the primary DNS server and immediately resolve
static assignments without zone transfers. Alcatel-Lucent also provides standards based (RFC 2136)
dynamic updates to cache. It supports dynamic updates to 4.9.7 and 8.x primary, secondary, master
and slave servers.
Dynamic DNS can also be performed from DHCP servers as addresses are leased, released, or renewed.
Depending on corporate procedures and processes, dynamic updates can be enabled, or disabled, from
all remote services. Control of dynamic updates can then be passed to the enterprise server where
intelligent processing of data can occur. An example of this processing would be determining if a host
name is unique and making appropriate changes as needed to enforce unique name requirements.
DHCP - Dynamic Host Configuration Protocol
Alcatel-Lucent‟s DHCP server is a high-performance, RFC-compliant (2131/2132) and scalable DHCP
solution to provide large corporations with dynamic allocation of addresses.
DHCP is supported on Sun, Windows and Linux and provides the following types of dynamic
allocations:
Dynamic DHCP – lease based
Manual DHCP – Fixed client-identifier to IP
