Knowledge Base & Operational DocumentationWhy Does a Domain Work on Wi-Fi but Not on a Mobile Network?
11/10/2026
A domain that resolves on one network but not another may be affected by cached DNS, different resolvers, IPv6 records, or a recent nameserver change.
What to check
Compare DNS answers and TTLs on both networks for A, AAAA, and CNAME records. Check authoritative nameservers and test whether the problem affects the apex, www host, or a specific service.
Recommended next step
Correct inconsistent records at the authoritative source and allow for resolver caching. Informatix Systems can investigate domain, DNS, and email configuration.
