You can capture DNS queries for all domains or only for specific ones.

The following are characteristics of query capture behavior:

- You can apply the **Bulk Add Domains** feature to tailor capturing of queries to a specific subset of domains or zones.
- When NIOS is capturing DNS queries, it matches a specified domain’s name and everything that belongs to the domain. For example, when you specify `foo.com` as the domain, NIOS captures queries sent to `foo.com`, `mail.foo.com`, and `ftp.foo.com`.

- NIOS captures queries to domains for which a name server is authoritative.
- NIOS captures recursive queries.

**NOTE:** This feature does **not** support wildcard characters or regular expressions.
