iNetwork Tools for Mac

From Security Focus Europe:

iNetwork Tools is a collection of useful utilities that include the following: 1. Network Information - general information about your network such as: local ip, gateway ip, gateway mac, broadcast ip and external ip. 2. Whois - is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information. The protocol stores and delivers database content in a human-readable format. 3. NSLookup - tool available for many computer operating systems for querying the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record. NSLookup uses the operating system's local Domain Name System resolver library to perform its queries. 4. Traceroute - is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. Traceroute sends a sequence of Internet Control Message Protocol (ICMP) echo request packets addressed to a destination host. Determining the intermediate routers traversed involves adjusting the time-to-live (TTL), aka hop limit, Internet Protocol parameter. 5. Ping - is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer. 6. Spam Check - this test will check a IP address against 13 DNS based email blacklists. (Commonly called Realtime blacklist, DNSBL or RBL). If your IP address has been blacklisted, some email you send may not be delivered. Email blacklists are a common way of reducing spam. 7. IP to Country - this tool displays the country of the IP address provided. 8. Port Scan - builtin remote port scanner. 9. Port Search - this tool search the port number provided to retrieve it's common service name or application name. 10. Local Port Scan - this tool displays your local ports that are open. You will get an extra security layer by keeping an eye from hacker that could gain remote access to your Mac using the opened ports. 11. Established Connections - this tool displays your active connections. You can easy see if your Mac is connected to a third party unknown IP.
