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 DNS Library is a COM object that makes dynamic DNS updates to BIND, Microsoft and other RFC-2136-compatible DNS servers possible from most languages in an easy way. The library supports the following record types: A, MX, SRV, NS, CNAME, PTR, TXT. The library implements 5 components: DnsLibrary.Server, DnsLibrary.Resolver, DnsLibrary.Authentication, DnsLibrary.ResourceRecord, DnsLibrary.ResourceRecordSet. Secure updates supported.

DynSite automatically updates your dynamic IP address every time it changes on one or many dynamic DNS services or by email. This allows anyone to connect to the servers running on your own computer using a fully qualified domain name. Since your host name never changes it makes accessing your servers much easier than using your IP address which changes each time you reconnect. This is also useful when you want to remotely control your PC.

Dynamic Update Tester is an application to test dynamic updates (RFC2136) on DNS servers. The latest version supports secure updates using transaction signatures (RFC2845). This is a test application not an automatic IP updater. For an advanced dynamic IP updater please try my DynSite program available at http://noeld.com/dynsite.asp

With WinIP, your machine will get a fully qualified domain name. Even if your computer's internet address is dynamically assigned, people can connect to your machine's FTP, WWW, IRC or other server by using your single hostname, recognized on the entire Internet. WinIP can manage multiple hostnames pointing to different IP addresses.
