«Перекопав» оба маркета приложений (App Store и Google Play) в поисках бесплатного и простого инструмента, для работы с сетью, был всё-таки найден заветный линк:
http://networktools.he.net/
Есть IP-калькулятор, поиск информации о DNS-записи, тест iperf, трассировка маршрута, проверка доступности узла(ping), сканер портов.
Всё, что умеет:
- Interface Information: Get information regarding your device's current network state.
- ARP / NDP: Lookup local devices found on your network using either ARP (IPv4) or NDP (IPv6).
- DNS lookup: Search for a server's DNS zone records such as SOA, NS, A, AAAA, MX, TXT, and rDNS.
- IP Calculator: Calculate the Netmask, Wildcard, Network, Host range, and Broadcast for a given subnet
- iperf (v2 and v3): Run TCP and UDP performance tests
- One Time Password: Manage time (TOTP) and counter (HOTP) based OTP passwords. Uses iCloud Keychain sync (if enabled) on iOS devices.
- Ping: Send ICMP packets to a single IPv4/v6 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 custom or pre-defined TCP ports on any server.
- SSL/TLS Information: Check used protocol, ciphers and certificate information.
- Whois: Get information regarding domain registration.
