Why does ipnow.kr show Cloudflare instead of my ISP?
ipnow.kr shows Cloudflare when your traffic exits through Cloudflare's network, AS13335, rather than your home connection. This usually means a VPN, proxy, iCloud Private Relay, or corporate network is routing you through Cloudflare, since it is not itself a home internet provider.

What is Cloudflare?
Cloudflare is a large global network and cloud services company best known for its content delivery network (CDN), DDoS protection, and the public DNS resolver 1.1.1.1. It is not a home or mobile internet provider, so no one signs up with Cloudflare for a residential internet line the way they would with KT or SK Broadband.
Because Cloudflare routes traffic for millions of websites, VPN services, and privacy tools, seeing "Cloudflare" as your ISP on ipnow.kr means the connection is passing through one of Cloudflare's servers rather than going straight from your device to the internet.
Why does my IP show Cloudflare?
The most common reason is a VPN or proxy service whose exit server is hosted on Cloudflare's network, which replaces your real ISP with Cloudflare in any IP lookup.
On iPhone or Mac, Apple's iCloud Private Relay feature routes some of your browsing through Cloudflare (or Akamai) servers as a privacy measure, which can make Cloudflare appear even without a traditional VPN. A corporate or school network using a Cloudflare-based security or Zero Trust gateway can produce the same result. Less commonly, the visitor is not a person's browser at all but a bot, script, or server running on Cloudflare's infrastructure. If you are unsure which applies to you, check that your VPN works to test whether a VPN or relay is active.

What is Cloudflare's ASN, and what DNS does it run?
Cloudflare's Autonomous System Number is AS13335, the identifier that marks a block of addresses as part of Cloudflare's network. See what is an ASN for a general explanation of ASNs.
Cloudflare also operates its own public DNS resolver, 1.1.1.1 and 1.0.0.1, which is separate from acting as your ISP; using Cloudflare's DNS does not by itself change the ISP shown on an IP lookup like ipnow.kr, since DNS and your actual IP address are handled independently.
How do I confirm this on ipnow.kr?
Open the ipnow.kr homepage with and without your VPN, proxy or Private Relay turned on, and compare the ISP and ASN fields; if Cloudflare and AS13335 appear only while it is on, that confirms your traffic is being routed through Cloudflare. If the shown location also changes, why your IP location can be wrong explains why a VPN or relay can make your location look completely different from where you actually are.

Frequently asked questions
Does using 1.1.1.1 as my DNS make my ISP show as Cloudflare?
No. Changing your DNS resolver to Cloudflare's 1.1.1.1 does not change your public IP address, so your real ISP still shows on ipnow.kr; only routing your actual traffic through Cloudflare, such as via a VPN or Private Relay, does that.
Why does my iPhone show Cloudflare as my ISP?
If iCloud Private Relay is turned on, Apple routes some of your web traffic through Cloudflare or Akamai servers for privacy, which can make Cloudflare appear as your ISP even though your real connection is a normal home or mobile line.
Is it bad that my IP shows Cloudflare?
Not necessarily. It usually just means a privacy or security tool such as a VPN, Private Relay, or a corporate gateway is in use, which is a normal and often intentional part of how you are browsing.
How is Cloudflare different from Amazon AWS or Google as a network?
All three run large cloud networks that can appear as your ISP when you use a VPN, proxy or bot hosted on them, but Cloudflare is best known for its CDN and DNS service, while Amazon AWS and Google are best known for general-purpose cloud computing.
