The Capibara Distributed URL Cloaking Kit is a reliable URL cloaking system using low QOS hosts and lines such as home PCs and DSL or cable connections. CDUCK combines DNS server/Web server functionality and a strict security model for the creation of reliable and safe domain Web cloaking.
Chaosmap is an information gathering tool and DNS, Whois, and Web server scanner. It can be used to look up DNS names with a dictionary with or without using a salt. Salting for DNS means it will append numbers from 1-9 to the name in the dictionary with or without a - and _ or a leading 0. Salting for Web stuff will try double slashes and some directory traversal tricks. It performs reverse DNS lookups of a whole IP range (with optional Whois lookup) and dictionary scans for hidden paths on one Web server or a range of IP addresses. Optionally you can encode a path with URL encoding use Google dict lookup mode to find the path on Google and only query the Webserver if there are no search results. It can also extract email addresses from domains using a Google search or perform a list of Google Hacking queries on your domain.
DNRD is a proxy DNS daemon. It supports several forward servers for redundancy and/or load-balancing. DNS queries for specific domains can be forwarded to a specific group of DNS servers (with redundancy and load balancing) for that domain. It is very useful in VPN and dialup environments but can also be used as a DNS cache or ad-blocker for networks and workstations.
Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP server. It is designed to provide DNS and (optionally) DHCP to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.
Network Query Tool (NQT) is a one-stop solution for getting information about a domain or IP address. Instead of manually using different Unix commands or visiting numerous Web sites to investigate a host, just load Network Query Tool and enter the hostname or IP. NQT does the rest. It supports a large number of TLDs and ccTLDs.
NicTool is a DNS management suite with support for various DNS servers (djbdns, BIND, PowerDNS), SQL data storage, DNS entry parsing (RFC 1034 & 1035 compliance), tiered and delegated permissions so you can safely grant access to clients and admins, giving them only the permissions they need. Humans interact via the Web interface, and an API is used for scripting mass updates, DNS templates, provisioning, and more. All changes are logged to easily track change history and see who changed what, and when.
