You can view all details for a specific zone via the NS1 portal or API.
To view detailed information about a zone in the NS1 portal, log into the portal and navigate to DNS > Zones.

Use the up/down arrows on your keyboard to move up or down the list of zones. Alternatively, you can click the whitespace next to the zone name to select it. A summary of details for the selected zone appears in the right-side panel which includes a list of associated records, activity log, and settings.

-
Records - This tab shows a list of DNS records associated with the selected zone — including the record type, domain, and TTL value.
-
Activity log - This tab provides a log of recent activity related to the selected zone.
-
Settings - This tab shows a summary of zone settings, including the date and time the zone was created and last modified, the zone's SOA TTL value, serial number, and DNS networks on which the zone is published.
Optionally, you can view and edit the tags associated with this zone. Each tag consists of a key-value pair (i.e., a "name" (required) and a "value" (optional)). You can apply one or more custom tags to zones in order to simplify DNS search and management.
To add a new tag, click Add a new tag. Then, enter a name for the tag (i.e., a key or property) and (optionally) an associated value.
Once complete, click the + button to apply the tag to the zone.
From the list of DNS zones, you can drill down to view more granular details about a zone by clicking the zone name. Note the breadcrumb menu at the top of the page which tells you what zone you are viewing.
The first page you see when drilling into a zone's details is the Records page. At the top, you can see a graph showing queries per second (QPS) against the zone over the last 24 hours. If the zone is published to multiple networks, multiple color-coded data sets will appear.

If you scroll down, you can see a list of DNS records associated with this zone. You can search the list of records using the search, sort, and filter tools — allowing you to filter the list by domain name, tag(s), record type, or record configurations. Additionally, from this page, you can create a new record within the zone or create a linked record.

Right above the list of DNS records is an option to select multiple records from the list to perform bulk actions, like deleting multiple records at once.

Additionally, you can click Show Activity to view record-level QPS statistics for a selected zone. Note that you can use the up and down arrow keys to navigate the list of records.

Similar to the Zones page, when a record is selected, information about that record appears in the right-side panel. The Answers tab shows you a list of answers corresponding to the selected record.

The Settings tab provides general information about the record, including when it was created and last updated. You can apply one or more tags to a record by clicking Add a new tag.

You can click the name of a record from the list to view more details, add answers to the record, etc.
After drilling into the zone details, you can click the Zone Settings tab to view or edit the zone configuration, including the DNS network(s) on which the zone is published and any associated DNS views.

Depending on the type of zone you are viewing, you can view different configuration settings related to the zone (e.g., SOA TTL and basic information for primary zones, associated primaries for secondary zones, DNSSEC, etc.). You can modify most of the zone settings directly from this page. Refer to Edit zone settings for details.
Note that you can also delete the zone by scrolling to the bottom of the page and clicking Delete zone and confirming the change.

The Zone Transfers tab contains any outgoing zone transfers configured for the zone. In other words, it lists the secondary IPs to which this zone is primary. Note that the concept of a "primary" zone can be misleading because you can enable outgoing zone transfers from a secondary zone hosted by NS1 to additional "secondaries" (i.e., tertiary zones).

Refer to this article to learn more about enabling outgoing zone transfers.
Click the Nameservers tab to view a list of NS1 Managed DNS nameservers that have been assigned to the zone. Note that it does not include custom nameservers corresponding to NS1 edge networks or dedicated namespaces.

Execute the command below to view details about a specific zone — replacing <zone_name>
in the URL path with the unique zone name. In most cases, the zone name is the same as the zone FQDN.
curl -X GET -H "X-NSONE-Key: $NSONE_API_KEY" https://api.nsone.net/v1/zones/<zone_name>
