7 Professional Tools for Comprehensive Network Diagnostics
Quickly test target server network latency and connectivity using ICMP protocol. Supports custom packet size and count, with real-time latency statistics (min/max/avg) and packet loss rate. Ideal for network troubleshooting, server performance evaluation, and daily network diagnostics.
Detect connectivity and response time of a specific port on a target host via TCP protocol. Ideal for verifying if a service port is open, testing firewall rules, and network detection when ICMP is disabled. Supports common port presets and custom port input.
Comprehensive detection of website HTTP response status, load time, redirect chain, and SSL certificate info. Supports GET/HEAD request methods with response header details. Ideal for website availability monitoring, performance optimization, and HTTPS configuration verification.
Query domain DNS records online, supporting A, AAAA, CNAME, MX, TXT, NS and more record types. Compare results across different DNS servers to troubleshoot DNS issues and analyze CDN node distribution. Provides visual representation of query results.
Combining Ping and Traceroute, trace the network path of packets in real time. Shows IP address, hostname, latency, and packet loss for each hop. Ideal for locating network bottlenecks, analyzing cross-border routing issues, and ISP fault diagnosis.
Batch scan the online status of all IPs within a specified CIDR subnet. Supports custom scan ranges and concurrency, quickly generating a list of available IPs. Ideal for network asset discovery, IP resource management, and security auditing.
Online detection of open TCP ports and services on a target host. Supports quick scanning of common ports and custom port range scanning. Identifies service types to help discover potential security risks and verify service configurations.
