ByteVirt Korea VPS Review: China-Optimized Routes with Netflix Unlock

If you're hunting for a Korea VPS that actually works well with China mainland networks, ByteVirt's new KR-China Optimized lineup might be worth a look. We're talking optimized routes for all three major Chinese carriers, up to 300Mbps bandwidth, and Netflix Korea unlock right out of the box. Let's see if this thing holds up under real testing.

What is ByteVirt?

ByteVirt showed up in 2023, run by Chinese operators who seem to know what they're doing. They've got VPS locations across Hong Kong, Singapore, Japan, Los Angeles, Turkey, and Taiwan, with some budget-friendly NAT options if you're into that. Now they've rolled out their Korea offering with mainland-optimized routes.

The upstream provider is MOACK. You get both IPv4 and IPv6. Here's how the routing works: China Telecom traffic goes through AS4134, China Unicom uses AS4837, and China Mobile runs on CMI. Pretty straightforward setup.

Pricing and Specs

The entry-level KR-China Optimized plan starts at $13.50 for six months (20% off launch pricing). Here's what you get:

• 1 vCPU (Intel Xeon E5-2680 v4, fair share)

• 512MB RAM

• 15GB SSD storage

• 1 IPv4 + 1 IPv6 /64

• 500GB monthly traffic @ 200Mbps

• KVM virtualization

• Seoul location

• 3 snapshots and 1 backup included

System Performance

The test machine ran Debian 12 on a 6.1 kernel with BBR congestion control enabled. Disk I/O averaged around 189.7 MB/s across three runs - nothing spectacular, but solid enough for most use cases. The CPU flags show AES-NI and virtualization enabled, which is nice if you're running nested containers or need hardware encryption.

Streaming and Content Access

Netflix Korea unlocked without issues on both IPv4 and IPv6. YouTube Premium worked fine, routing through GB for IPv6. Interestingly, Bilibili identified the connection as Hong Kong/Macau/Taiwan only - not full mainland access, but useful if you need regional content.

Here's what unlocked in testing:

• Netflix Korea (native and DNS unlock)

• YouTube Premium

• Amazon Prime Video (HK region)

• iQIYI International (HK)

• Spotify (HK registration)

• Disney+ (Korea region)

ChatGPT was app-only via Hong Kong IP. TikTok didn't work, and neither did TVBAnywhere+.

Network Performance

Latency to China

Domestic China latency ranged from 23ms (Shanghai Telecom) to around 60ms for other regions. That's pretty decent for Korea. During testing, there was minimal packet loss - mostly single-digit percentages or zero loss on major routes.

Speed Tests

Global speed tests showed consistent performance:

• Shanghai Mobile: 208.92 Mbps up / 205.59 Mbps down (32.68ms)

• Hangzhou Telecom: 203.97 Mbps up / 201.25 Mbps down (59.94ms)

• Tokyo: 197.63 Mbps up / 196.52 Mbps down (30.75ms)

• Los Angeles: 197.48 Mbps up / 201.15 Mbps down (137.18ms)

European routes were slower as expected, with London and Frankfurt hovering around 136-148 Mbps upload speeds.

Routing Details

Return Routes (From Korea to China)

Shanghai Telecom: Goes through AS4134 backbone, landing in Shanghai with about 35ms latency. Pretty clean path.

Shanghai Unicom: Uses AS4837 (CU169 backbone) with around 48ms to Shanghai. Six hops through Unicom infrastructure.

Shanghai Mobile: CMI international routing through Seoul, then straight to Shanghai mobile network. About 27-31ms end-to-end.

Outbound Routes (From China to Korea)

China Telecom routes through Shanghai backbone (AS4812) with 25-43ms reaching Seoul. Unicom paths through Beijing sometimes, adding a few milliseconds. Mobile routes are the most direct, typically staying under 35ms.

IP Quality

The IPs tested clean - no major blacklist issues detected. WHOIS shows proper MOACK allocation under AS138195. The IPv6 block is from the 2a12:bec0 range.

Worth It?

For $13.50 per six months, you're getting a Korea VPS with legitimately optimized China routes and decent streaming unlocks. The bandwidth caps at 200Mbps on the base plan (upgrades available to 300Mbps), which is realistic for the price point.

The routing isn't magical - you're still going through international pipes - but it's way better than random Korea VPS providers who dump everything onto congested consumer ISP routes. The MOACK upstream seems well-peered with Chinese carriers.

If you need a Korea presence for regional content access or want lower latency to China mainland compared to US or EU locations, this setup makes sense. The included snapshots and backup are nice touches for a budget VPS. Just know you're working with 512MB RAM on the entry tier, so plan your workload accordingly.

👉 If cross-border connectivity between Korea and China matters for your projects, ByteVirt's optimized routes deliver measurably better performance than generic solutions. Worth testing during their launch discount period.
