Knowledge
Practical guides to servers, networks and IP resources.
What should you back up on a server—and can you restore it?
Check application files, databases, uploads and configuration, understand backup locations, and use an isolated restore test and pre-recovery checklist to verify readiness.
How to read reverse DNS results: what if there’s no PTR record?
Read PTR names, DNS status and TTL without confusing a missing record with a failed lookup. Learn what reverse DNS means for websites, email and provider changes.
How fast can you download on a 100 Mbps connection?
100 Mbps converts to 12.5 decimal MB/s, not a guaranteed download rate. Compare units, transfer conditions and data allowances before choosing a server.
How to test a server’s network before buying
Try any dedicated server free for 48 hours, including Hong Kong, with no deposit or approval. Cloud servers are excluded. Check Ping, MTR and application use from your users’ networks.
CN2, CMI and BGP: what to check
Look beyond route labels to traffic direction, carriers and test results.
How to choose cloud server specs: CPU, RAM and storage
Check CPU, memory, storage and network requirements, compare VPS and dedicated servers, and separate introductory, renewal and optional charges.
Hong Kong, Los Angeles or Tokyo?
Compare audience location alongside the available routes.
How to read an IP lookup: country, ASN and network organization
Learn what country, ASN, network organization and organization domain mean in an IP lookup, and what they cannot establish about residential status, server location or performance.
Cloud server costs explained: compute, storage, data transfer and renewals
Check what a quote includes, identify separate resource charges and later costs, and compare cloud and monthly server plans on the same basis.
Why Do Online and Local Ping Results Differ?
Understand how probe location, routes and destination IPs affect ping results, which test to use, and what a three-packet sample can tell you.
Does packet loss at an intermediate MTR hop mean there’s a network problem?
Read intermediate-hop loss alongside the destination, later hops and application symptoms. Understand response limits, three-packet samples and what to save for support.
