	IE Timeout Tuner  License: Freeware
	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. Internet Explorer does not honor and does not use the TTL (time to live) value provided in DNS records. Instead it caches all DNS records for a fixed period of time (as per this setting) - with one exception: After Internet Explorer has fetched a web-page, it does not immediately close the TCP connection to the web-server. By keeping the connection open, following requests to the same web-server can be executed faster. This is known as "keep alive". This setting affects both DNS caching and server connections ("keep alive") timeouts. Internet Explorer does not refresh DNS records if another page is requested from the same server domain name within this time interval - even if the DNS Cache Timeout setting has a lower value. In other words, DNS records timeout according to the higher value of this and the DNS Cache Timeout setting. However, server connections appear to timeout according to the lower value of this and the Keep Alive Timeout setting. So for the most predictable results, the value of this setting should be set lower than or equal to the DNS Cache Timeout setting, and higher than or equal to the Keep Alive Timeout setting.

	TSIG Key Generator  License: Freeware
	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. You can create a key value using four different methods: Random 128 bit value, random 256 bit value, random 512 bit value or from pass-phrase (MD5-hash). The key value generation functionality of TSIG Key Generator is already built into Simple DNS Plus and Simple Failover from JH Software. Author: JH Software| Date: 21-10-2004 | Size: 143 KB

	iNetQuery  License: Freeware
	iNetQuery is a powerful Internet utility for network monitoring for MS Windows platforms. Special query features, like DNS, Whois or NetStat, can be used to determine detailed information about domains, hostnames or network providers. Utiltities like Ping or Traceroute are suitable to find out if a remote host is reachable or to check your network performance. iNetQuery captures all active network connections, as well as the running tasks on the local system. Unwanted data transactions and activities of unknown applications, e.g. trojans, can be detected and denied in this way. Additional utilities can query special DNS records like SPF (Sender Policy Framework) or Open-Relay databases to find blacklisteted hostnames. A status panel shows detailed information about installed network interfaces. Adapter properties and activities, as well as statitistics about tranferred bytes and packets, are shown there. A special report engine can create detailed reports about domains or hostnames. Information about domain owners, network providers and responsible persons will be determined automatically and displayed in a detailed summary.

	Advanced Subnet Calculator  License: Freeware
	Are you tired of subnet calculators with limitations? Other subnet calculators only offer one function, do not allow exporting, and usually require a purchase to enable all the features. The SolarWinds Advanced Subnet Calculator is completely free and fully functional. In fact, it actually delivers four tools in one: Address Details - provides forward and reverse DNS resolution, response time, address translation (hexadecimal and binary) and address class information. SolarWinds Advanced Subnet Calculator also supports resolution of IP address owners to aid in managing your network. Classful Subnet Creator - calculates subnets based on subnet mask, mask bits, host bits, number of subnets and hosts per subnet. SolarWinds Advanced Subnet Calculator also generates a range of subnets based on these settings. CIDR Calculator - includes full support for Classless Inter-Domain Routing (CIDR). Use of CIDR addresses reduce the size of routing tables and make more IP addresses available within organizations. This CIDR classless subnetting feature is particularly useful for ISPs, universities, or corporations with many Class C addresses. Subnet Addresses - generates a list of addresses for any subnet, which then becomes the working document from which to assign current and future IP addresses. You can even assign addresses within SolarWinds Advanced Subnet Calculator and then print the worksheets. To expand the capability of our free Advanced Subnet Calculator, you can also download and evaluate the IP Address Management application contained in the SolarWinds Engineer's Toolset. With the IP Address Management application, you no longer have to rely on Excel® spreadsheets or paper documents to track and manage your installed and available IP addresses – we’re sure if you try it, you’ll love it!

	DNS Thing  License: Freeware
	DNS Thing is a free utility that provides Windows users with a way to make common DNS queries using a graphical user interface. It can provide frequently queried information like looking up the IP address for a hostname or determining the MX record for a domain. DNS Thing uses the Nslookup utility as an underlying technology to perform the actual DNS queries. However, by providing a graphical front-end, it vastly improves its usability and makes accessing more advanced results such as Sender Policy Framework anti-spam data and time-to-live (TTL) information for queries practical.
