Read web-collected China Unicom DNS-related IPv4 records, ranges and location labels. Original source, collection date, public access and availability are unverified.
Static address directory. Connectivity, resolution speed and access from your network are not checked.
Source label: web-collected. The original publisher and collection date have not been verified. Region labels retain the source wording where no translation is available; access and resolver availability are unverified.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This page displays static IPv4 records labelled as DNS-related to China Unicom networks. Each row has a start IP, an end IP, and a recorded location label. The record set includes single-address entries where both IP fields match and interval entries where they differ. The label is part of the saved record; it is not a live location lookup or confirmation from the network operator.
The records are described as web-collected. Their original publisher and collection date are unknown, and no resolver health, response time, current assignment, or public access test has been performed. “China Unicom” in a label therefore identifies what the directory says, not a certification that the operator published, owns, or currently operates that address. Use it as a historical or troubleshooting clue when reviewing an existing configuration.
An address interval records two endpoints. It does not establish that every address between them is a working DNS resolver. A DNS resolver answers domain-name queries; this table itself does not send queries or test whether a listed address responds.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Read Start IP and End IP together with Recorded location. Keep the label beside an address when saving notes so that the record’s context is not lost.
The filter matches displayed text such as a location label or an IP string. It is not an IP-range containment search: an address lying between two endpoints may not match either endpoint string.
Sort a column to compare its values and use the table’s page controls to inspect additional records. The default order starts with the Start IP field.
Table export is gated by account access or membership. If export is unavailable, use the on-screen rows to inspect the directory; no scan or validation is performed by exporting.
Use cases
See how the tool fits into real work and everyday tasks.
An administrator reviewing an older configuration can compare a saved IPv4 address and location note with the directory, then verify its purpose through the organization’s current network documentation.
A user who sees a campus or regional label can provide the row to the network team as a question. The label alone does not show that the address is reachable from outside that network.
A researcher can inspect start and end values while preserving the original order and note that provenance is incomplete. Do not convert a range into a list of assumed resolvers.
Q&A
Find concise answers to common questions and confusing cases.
The directory does not establish that. Public access is unverified, and some network resolvers may only answer within a particular provider or organization’s network.
No. The row gives start and end values only. It is not evidence that intermediate addresses provide DNS service.
No. It is a saved text label with unknown original source and collection date, not a current geolocation or operator confirmation.
No. The page presents records and does not run DNS lookups, availability checks, or speed tests.
Notes
Review scope, result limitations, and important precautions before use.
This is a static, web-collected directory with unverified provenance. It does not promise completeness, freshness, operator endorsement, or availability from your network. A resolver may be restricted to a provider, region, campus, or other managed network. Confirm the intended use and access scope with your network operator before configuring a device.
Do not rely on the labels to establish current ownership or safety, and do not replace a working DNS configuration solely because an address appears here. Keep a copy of your existing settings and follow the instructions supplied for the network you actually use.
