Use this tool to perform lookups against the local and/or other DNS servers.
See Look Up Types for details.
The DNS Look Up window consists of a Menu, a Toolbar, Domain name/Server entry fields, Result display area, and a Status Bar.
| • | File menu |
| • | Look Up Choose one of the sub-items to do a specific look up type. |
| • | Stop Query Cancel to current DNS look up. |
| • | Exit Closes the DNS Look Up window. |
| • | Edit menu |
| • | Copy selection Copy the current selection in the result display area to the Windows clipboard. |
| • | Copy full response Copy everything in the result display area to the Windows clipboard. |
| • | View menu |
| • | IDN Native Characters Enables/disables display of native characters for IDNs. |
| • | Server selection Shows/hides the server entry field. |
| • | Toolbar Shows/hides the toolbar. |
| • | Status bar Shows/hides the status bar. |
| • | Options menu |
| • | Request recursion When checked (default), the DNS server will be asked to resolve the query if it doesn't have the answer in cache. Not all DNS servers accepts requests for recursion (also an option in the Simple DNS Plus). If a DNS server does not offer recursion, it will usually still respond to the request, but may only offer references to other DNS servers. |
| • | Use TCP (virtual circuit) Most DNS requests, except for zone transfers, are sent over UDP. However in some situations it can beneficial to test if a DNS server also responds via TCP (which it should). This is also know as VC or "virtual circuit" in the classic NSLOOKUP command line tool. |
| • | UDP payload size Specify the maximum response packet size for UDP requests (an "EDNS0" option). This can be useful for testing certain requests which return large response messages. For example, IPv6 records were recently added for the Internet .com and .net top level names, making the full referral message for these domains larger than the standard 512 DNS message size. |

Domain name/Server entry fields
Enter the domain name to look up.
If "Server selection" is enabled in the View menu you can also specify the server to do the look up against.
If "Auto" is checked, the tool will automatically try to determine the server name / IP addresses (recommended for WHOIS lookups).
