4 天前开始,出现 DNS 被抢答的情况,这几天或轻或重,一直存在着。
如果挂全局代理,除了受地域限制的(比如在线看视频)不能访问外,所有访问是正常的。
随便截个测试的屏:
附 PowerShell 代码:
# Requires PowerShell 3.0 or above function Test-NSError { if ($count -ne 0) { Remove-Variable count -ErrorAction SilentlyContinue } $count++ Write-Host -ForegroundColor Cyan "Loop $count`:" $direct = Resolve-DnsName 10000.gd.cn foreach ( $Address in $($direct.IP4Address)){ Write-Host -ForegroundColor Red "`tDirectly resolve 10000.gd.cn`: $Address." } $withServer = Resolve-DnsName 10000.gd.cn -Server 1.1.1.1 Write-Host -ForegroundColor Green "`tResolve 10000.gd.cn by 1.1.1.1`: $($withServer.IP4Address)." Write-Host -ForegroundColor Gray "------------------------------------------------" Start-Sleep -Seconds 30 Test-DNSError }
