Network diagnostics guides and tutorials
Find the AS number of any IP address with whois, bgp.he.net, and RIPEstat. Learn what ASNs reveal about network ownership, BGP peering, and routing behavior.
Learn how to trace a DNS resolution step by step with dig +trace, nslookup, and drill. Debug NXDOMAIN, slow lookups, and propagation issues with practical examples.
Learn how traceroute discovers the network path hop by hop. Understand TTL, ICMP, and how to interpret results.
Struggling with lag and high ping in online games? Learn how to use traceroute to diagnose the exact cause of your latency, identify the problematic hop, and take action to fix it.
Compare the three traceroute protocols and learn when to use ICMP, UDP, or TCP for network diagnostics.
Practical strategies to identify and reduce network latency using traceroute, CDN optimization, and routing improvements.
How DevOps teams use traceroute, ping, and DNS tools to debug connectivity in multi-region deployments.
Compare the best traceroute tools in 2026 — from CLI to visual web platforms.
Understand how Autonomous System Numbers (ASN) and BGP routing determine the path your data takes across the internet, and why it matters for performance.
A practical guide to using traceroute to find network bottlenecks. Learn to interpret hop latency, detect congestion, and pinpoint performance issues.
Explore what causes network latency, how to measure it accurately, and practical strategies to reduce it for better application performance.
Compare traceroute and ping — two essential network diagnostic tools. Learn when to use each, what they reveal, and how they complement each other.
