The VPNs service providers also know this and have introduced a feature called Stealthing, Ghosting or VPN Obfuscation (terminology varies, but they generally mean the same thing).
Watoa huduma wa VPN pia wanajua hili na wameanzisha kipengele kiitwacho Stealthing, Ghosting au VPN Obfuscation (istilahi hutofautiana, lakini kwa ujumla zinamaanisha kitu kimoja).
