NetInfo

A System or Network Administrators best friend!

NetInfo is a simple tool for querying several network services on your iPhone or iPod Touch. NetInfo gives the user the ability to query Whois domain registration databases, DNS records, and execute ICMP ping on a given host or domain name. NetInfo provides a simple yet elegant user interface to allow the user to quickly visualize the results of each query type.

WHOIS QUERY

The Whois query allows the user to determine ownership and/or availability of a given domain name. Phone numbers, hostnames and email addresses are automatically highlighted and hyperlinked. This allows a user to quickly surf to a linked page in Safari. It also allows a user to quickly contact an administrative, billing or technical entity directly by email or telephone. The Whois query user interface takes advantage of iPhone OS 3.0 allowing the user to copy and paste information from query results from NetInfo to any other iPhone OS 3.0 application.

ICMP PING QUERY

NetInfo implements a simple ICMP (ECHO_REQUEST/ECHO_REPLY) client. Given a hostname or IP address NetInfo will provide results of a ICMP ping query in a simple list view. Each list entry will indicate the sequence number of the reply from the host. It will also indicate the user the IP address of the target host and response time in milliseconds.

DNS QUERY

The DNS query reports several important pieces of information about a given host. Given a hostname NetInfo will determine the official name for the host, along with any aliases. NetInfo will provide all known IP addresses for the host. It will also provide MX records (with priorities) for any mail exchangers for a given host or domain. NetInfo will also notify the user of whether or not the answer from DNS was authoritative or not. All of this information is presented to user in a standard table view allowing the user to quickly find the information they need.

NetInfos DNS query is also able to do reverse, or hostname to IP address, lookups.

NETWORK REACHABILITY NOTIFICATION

NetInfo keeps an eye on the your iPhones network connections and will notify you when you lose connectivity. If you lose connectivity with both your WAN and Wifi connection, you will be presented with an alert notifying you of the change. This will allow you to save some time when successful queries are not possible.

NetInfo was designed for iPhone OS 3.0.
