This tool can generate a TSIG key value (base64) for you very easily. The key value complies with RFC2845. Secret Key Transaction Authentication for DNS (TSIG) is a secure method of authenticating clients making dynamic DNS update requests. The client application and the DNS server share a secret key value which is used to sign (HMAC-MD5) each update request. You can think of the key name as a user ID, and the key value as a password.

The simple yet powerful DNS server for Windows 9x/NT/2000/XP/2003
With Simple DNS Plus you can hosts your own domain name, or simply speed up Internet access by running your own DNS server.

PacketTrap (http://www.PacketTrap.com) DNS Audit is a utility that matches one or more IP addresses to their corresponding DNS names. The tool does forward lookups on the DNS name so you can ensure that the forward and reverse lookups match. The tool also displays NetBIOS, local host and lmhost file values for each IP.

Globesoft MultiDNS forwards DNS resolution requests to a list of secondary DNS servers, one by one, until the request successfully has been carried out and the name has been resolved. If any of the secondary DNS servers respond, but fail to resolve the name, then Globesoft MultiDNS proceeds with the next server in the list.

Interactive DNS Query is a program designed to allow you to perform a query of DNS records. It is similar to the unix "dig" or "nslookup" commands, and uses a convenient GUI interface. Interactive DNS Query allows you to query for all types of DNS records, including A, MX, TXT, NS, etc.

This tool can adjust 3 'hidden' registry settings of Internet Explorer to control caching of DNS records, server connection timeout, and caching of server information.

It can be useful to change these settings to very low values, especially when testing web-servers with quickly changing DNS records / IP addresses. For example in DNS Round Robin or Simple Failover setups.
- DNS Cache Timeout
- Keep Alive Timeout
- Server Info Timeout
