The zone page displays a summary of the contents of a DNS
zone. It lets you browse the contents
of a zone and select one of its domain names for viewing or editing.
The zone page navigation subsection contains the following functions:
Add resource record
After choosing a resource record type you will be transferred to a page where you
need to insert the necessary information for the selected record.
The available resource records are:
A
AAAA
AFSDB
A
CNAME
DHCID
DLV
HINFO
HIP
HTML
HTXT
ISDN
LOC
MX
NAPTR
NS
NSAP
RP
RT
SPF
SRV
SSHFP
TXT
WKS
X25
Add host
Displays an empty node page
for adding information about a new host, such as its IP address and
mail routing information.
Add multiple hosts
Like "Add host", but lets you conveniently add a whole series of
similar hosts. The name entered will be used as such for the first host,
and the subsequent host names will get a numerical suffix (or an existing
suffix will be incremented). The hosts will automatically be assigned
successive IP numbers, starting with the specified one.
Add mail route
Displays a form for defining a new name with a set of
MX records. This is useful for defining
the routing of mail addressed to a domain name that does not correspond
to a physical host. By entering the special name "*" it is
possible to define a set of wildcard
MX records.
Add comment
Displays a form for defining a new name with one or more
TXT records.
Add service
Displays a form for a new name with a set of
SRV records. This resource record set
is intended to specify location of services with load balancing and
priorities.
Add alias
Displays a form for creating a new alias (in other words, a new
domain name with a CNAME record).
Add delegation
Displays a form for delegating
a subdomain of the current zone, to make it separately maintained
with a set of name servers of its own.
Add delegations
Like "Add delegation", but lets you conveniently add a whole series of similar delegations.
The name entered will be used as such for the first delegation, and the subsequent delegation
names will get a numerical suffix (or an existing suffix will be incremented).
After asking for confirmation, destroys the entire zone and all its
contents.
There is a new checkbox for deleting reverse maps automatically,
it removes the PTR-records but not the reverse zone itself.
Copy zone
You can create a copy of the zone contents, a new zone, or a new view
of the zone.
Export master file
Lists the contents of the current zone in the standard RFC1035 master
file format. By using the "save" function of your web browser, you can
save the zone data for further processing by other DNS software that uses
the master file format.
Export hosts file
Lists the A records of the current zone in the /etc/hosts
format. By using the "save" function of your web browser, you can save
the zone data for further processing by other software that uses this file
format.
Bulk Changes
The bulk changes operation allows you to make mass changes in the
zone, such as replacing resource record contents or deleting hosts
matching a pattern.
Zone Statistics
Displays the summary of the DNS data
in this zone.
Settings
This page can be used to manipulate general
zone settings and,
in case of a DNSSEC-enabled zone, to access any signing keys associated with the zone.
The zone overview section contains a summary of zone's most commonly required information:
Zone type
Zone's status (whether it is enabled or disabled)
Serial number
Last modification date and time
The number of nodes contained within the zone
Zone's IP addresses
DNSSEC status and information
NSEC3 status and information
DNSSEC key list with names and information
Zone's primary and secondary name servers. NameSurfer tries to verify that all name servers have the same serial number.
For each server one of the following result will be displayed :
OK, serial numbers match
N/A, NameSurfer did not receive a reply from the name server
REFUSED, name server refused the query
NXDOMAIN, name server does not have the domain in question
If there is a mismatch between NameSurfer and the name server, SOA serial number received from the name server is displayed
Zone's remote secondary name servers
Sorting and filtering
You can view the zone data sorted either by name or by address by
clicking the underlined headers in the first row of the table.
The listing can be limited by first letter of node name by choosing the letter
on the Filter line above the listing table. On DNSSEC-enabled zones that use NSEC3
authenticated denial of existence there are a lot of special nodes that only contain NSEC3 records
and are not useful for normal DNS management - the Show/Hide NSEC3 records toggle on the
Filter line can be used to select whether these nodes should be shown or not.
The zone data
The bulk of the form consists of a table summarizing the contents of the
zone, one line per name.
The table may contain some or all of the following columns, depending on
the display preferences settings.
Some of the columns may also be missing when using a web browser lacking
HTML table support.
The data shown in this column varies depending on the types of
records stored under the name. If the name is a host, the IP address(es)
is (are) shown here. If the name is an alias, the canonical name is shown,
etc.
The private comment data (HTXT and
HTML records) of the name, if any.
Due to limited screen space, only the first few characters of each HTXT
record are displayed. HTML records are displayed in full.
Tags can be added to zones by clicking the modify-link under the tags-section in the
zone overview. Note, that if a user's access to objects (zones) has been restricted (in
the user's groups), then only tags to which the user has access to can be added to zones.
Please see the separate documentation about
tagging for more information.
Full access level to zones overrides any tag-restrictions to objects (zones).
