HE.NET Network Tools vs UDP/TCP/REST Network Utility

This suite of networks tools implements most of the network diagnostics that you need as a Network Engineer or System Administrator. Please help us improve it by giving us feedback. + ARP / NDP: Lookup local devices found on your network using either ARP (IPv4) or NDP (IPv6). + Bonjour Browser: See what DNS-SD/Bonjour services are available on your network + DNS lookup: Search for a servers DNS zone records such as SOA, NS, A, AAAA, MX, PTR. + Interface Information: Get information regarding your device's current network state. + IP Calculator: Calculate the Netmask, Wildcard, Network, Host range, and Broadcast for a given subnet. + iperf: Check bandwidth against remote iperf services. + One Time Password: Securely store and view your TOTP and HOTP (two-factor authentication) codes. TOTP codes are available on the Apple Watch. + Ping: Send ICMP packets to a single IPv4/IPv6 address. + Ping Sweep: Send ICMP packets to an entire subnet range. + Traceroute: Find the route packets take to reach your destination. + Progressive Traceroute: Get detailed statistics for a given route. + Port Scan: Scan a list of TCP ports on any server. + Routing Table: See your local device's routing table. + SSL/TLS Information: Check available ciphers, protocols and what's being used when connecting to a remove service. + Whois: Get information regarding network resources. + NO ADS! Note: Recent iOS releases secure certain low-level network information, and as such will not be available in-app, such as MAC addresses for other network devices.

The only network utility application you will ever need: 1) UDP Send and/or receive datagrams in both string and hexadecimal format. You can send the datagrams to another instance of the application, a server that is set up to receive datagrams or to the same instance of the application. If you are receiving datagrams, you can specify any valid port to bind to. 2) TCP TCP Mode supports two (2) submodes: 1) TCP Client and TCP Server. TCP Client allows you to to connect to a TCP Server via specifying the remote host and port the server is operating on. Once connected, messages can be sent to the server; any responses will be displayed in the output view. 2) TCP Server allows you to create an instance of a tcp server operating on a port that is user configurable. Once one or more clients connect, messages can be sent to the set of connected clients. All responses from the client will be displayed in the output view. Messages and responses can be a utf8 string or raw data in hexadecimal (go to settings to configure format). 3) REST REST mode supports four (4) request method/verbs: GET, POST, PUT,DELETE. In 'GET' mode, given a url, will display the output in output view. In 'POST' and 'PUT' mode, given a url and a body (e.g. parameters), the output will be displayed in the output view. In all cases, the output can be formatted in RAW or JSON. JSON builder feature to easily build the request body is available if POST/PUT is selected. 4) Network Scanner Scan a single or a range of IP Addresses. Optionally, test if a port is open. Response of scan includes number of packets sent, received, lost, response time and status of port. By going to Settings/Info, you can specify the timeout period for ping and port scans. • Current private and public IP Address available in Settings/Info tab. • Network interfaces available in Settings/Info tab.
