Command

$ Get-DnsClientCache | Format-Table Entry, Data, TimeToLive -AutoSize

02What it does

Windows caches every DNS answer to speed up browsing, but a stale or poisoned cache entry can send you to the wrong server. Get-DnsClientCache lists each cached record, its data and remaining TimeToLive, so you can confirm whether a hostname is being answered from cache. If an entry is wrong, flush it with `ipconfig /flushdns` and resolve again.
