Will switching DNS to 1.1.1.1 unblock sites?

Sometimes. It defeats DNS-level blocks but nothing else. If the block is at the IP layer, SNI layer, or protocol layer, DNS changes don't help.

Are browser extensions enough?

For mild blocks on a corporate network, yes. For state-level filtering, no — most extensions are HTTP/SOCKS proxies that get fingerprinted quickly and don't protect non-browser traffic.

Is Tor a good general-purpose tool for blocked sites?

Tor is excellent for anonymity but its plain TCP entry points are easy to block. Wrapped variants (obfs4, snowflake) work but add latency. For everyday browsing, a Reality-based VPN is faster and less fragile.

How long does any one method keep working?

It varies. Reality has held up for two years and counting because there is no signature to write. Older transports (vanilla Shadowsocks, plain WireGuard, OpenVPN) tend to lose effectiveness in months to a year as DPI signatures roll out.

Is bypassing blocks legal?

Jurisdiction-dependent. In most countries using a VPN itself is legal. The activity you do over the VPN is governed by the same laws that apply without it. Check local rules; we can't advise on legality.

How blocks really work — four layers

Most "how to bypass blocks" articles assume the censor is doing the dumbest thing possible. In 2026 they almost never are. Blocks usually stack at four layers, and a workaround that defeats one will fail to the next.

Layer 1 — DNS hijack. Your ISP returns a wrong IP for the blocked domain. The cheapest, oldest method. Defeated by switching DNS to 1.1.1.1, 9.9.9.9, or DNS-over-HTTPS (DoH). Almost no large censor relies on DNS alone anymore.

Layer 2 — IP block. The site's IP addresses are dropped at the ISP edge. DNS workarounds don't help: even with the right IP, the packet never gets out. Defeated by routing through any endpoint that isn't blocked.

Layer 3 — SNI inspection. Your TLS hello includes the domain name in cleartext (the SNI field). DPI inspects it and drops the connection if the domain is on a list. ECH (Encrypted Client Hello) defeats this — but only if both your client and the destination support it, which is still patchy in 2026.

Layer 4 — Protocol fingerprinting. The censor doesn't care about your destination — it cares about how your traffic looks. OpenVPN, WireGuard, plain Shadowsocks, IKEv2 — all have recognisable handshake shapes. Once fingerprinted, the connection is throttled or dropped regardless of the destination IP. This is the layer that breaks every "just use a VPN" answer.

Methods that no longer work alone

Editing the hosts file. Defeats DNS hijack but not IP blocks. Useful only against the laziest filtering.

Switching to public DNS. Same story. Helps for cheap regional blocks; useless against any state-level filter.

HTTP-only proxies. Forces every site through plaintext intermediaries that themselves get blocked within hours. Also breaks every modern site that requires HTTPS.

"Free" web proxies (sites that load other sites in an iframe). The proxy site itself ends up on the blocklist almost immediately. They are also a privacy disaster — they see everything you do.

Browser-based "VPN" extensions. Most are HTTP/SOCKS proxies with a marketing skin. They fail at every layer above SNI inspection and don't cover non-browser traffic.

Tor over plain TCP. Easy to fingerprint by handshake. Works only if you wrap it in obfs4 or meek bridges, and even those need active maintenance.

Methods that still work

The list is short and converging.

VLESS+Reality. Carries traffic inside a real TLS 1.3 handshake to a real, popular website. To DPI, your connection is indistinguishable from someone browsing that website. No fixed handshake to fingerprint, no fake certificate to flag. Full protocol explainer.

Trojan-GFW. The conceptual sibling of Reality — also pretends to be HTTPS to a real site, with slightly different design choices. Still works in many regions, with similar caveats.

Hysteria2 / TUIC. QUIC-based protocols that exploit how DPI struggles with UDP at scale. Excellent throughput where they work; some networks block UDP/443 entirely.

Shadowsocks-2022 over a CDN. Used to be the workhorse before Reality. Still viable when fronted by a major CDN that the censor cannot afford to block wholesale.

Wrapped Tor (obfs4, meek, snowflake). Higher latency, but resistant for low-bandwidth use cases. Snowflake in particular makes blocking expensive because it routes through volunteer browser tabs.

Combining layers — why a smart client matters

A modern bypass tool isn't one protocol; it's a set of fallbacks. The client probes which transport is currently working from your network — TLS to a real cover SNI, then UDP if that fails, then a CDN-fronted endpoint as a third choice. The decision happens in milliseconds, transparent to the apps.

This is what VnePN does on the user-facing side. The subscription you import contains multiple endpoints; the client picks the one with the best handshake on your network and falls back automatically if conditions change. You see "VPN connected" — under the hood the protocol may have switched between morning and evening.

The other half is what does not go through the tunnel. Routing every packet through a VPN breaks domestic banking apps, government services, and local payment rails. Smart routing bypasses those automatically — Russian and ex-USSR banking IPs go direct, everything else through the tunnel. This sidesteps the most common failure mode of naive VPN setups.

When you don't need anything fancy

If your block is at the corporate Wi-Fi, school network, or a public hotspot — almost any VPN works. Those operators rely on cheap commercial filtering boxes that don't fingerprint at the protocol level. WireGuard or OpenVPN over TCP/443 is enough.

If your block is at the country edge — Russia, Iran, China, parts of the Gulf — you need at minimum VLESS+Reality, Trojan, or Hysteria. The protocols listed earlier were specifically designed against this category of block. Russia-specific guide · ChatGPT case study.

If your block is service-side (a website blocking your country's IP range) — any VPN with an exit node outside your country will do. The protocol matters less; pick by speed and the country list.
