Can someone find my exact address from my IP?

Almost never. IP geolocation databases map IPs to cities or regions, not street addresses. Mobile IPs are often accurate to a city at best; carrier-grade NAT can put you hundreds of kilometers away.

Why does my IP say a different country when I travel?

Because your provider routes traffic through an exit point in another country, or you're on CGNAT. Geolocation reflects the network, not the person.

Does a VPN hide my IP?

Yes — the site sees the VPN exit node's IP instead of yours. But the VPN provider sees your real IP, and fingerprinting (cookies, browser) still identifies you. VPNs are a privacy layer, not invisibility.

What Is My IP: ASN, Geo & VPN Detection Explained | yas.sh

Your public IP is a data package: address, ASN, ISP, city and timezone. Here's what each field means, how IP geolocation works, and how VPNs change the picture.

Open the What Is My IP tool and it tells you a lot about a little string of numbers: your IP, its IPv4/IPv6 form, the ASN and organization behind it, the city and country the databases associate with it, and your timezone. Here's what each field really is — and what it isn't.

The address itself: IPv4 vs IPv6

Your public IP is the address other servers use to send data back to you. Two families exist side by side:

IPv4 — 32-bit, 203.0.113.7. The internet ran out of fresh ones in 2011; everyone else is behind NAT or carrier-grade NAT.
IPv6 — 128-bit, 2001:db8::a:b:c:d. Plenty of room, but not universally deployed — which is why most users see IPv4 while their network is technically IPv6-capable.

The tool reports both when available and flags which family the request actually arrived over.

ASN and org: the who behind the address

Every IP belongs to a network operated by an organization — an Autonomous System. Each AS has a public number:

AS15169 — Google LLC
AS13335 — Cloudflare
AS16509 — Amazon (AWS)
AS8075 — Microsoft

When you connect from home, your IP belongs to your ISP's AS; from a coffee shop, to the shop's provider; through a VPN, to the VPN provider's AS. The ASN + org pair is often more identifying than the raw IP: services use it for abuse reports, geo-targeting and bot detection.

City, region, country: what geolocation really is

Geolocation databases (MaxMind, ip2location, ipinfo) map IP ranges to coordinates. The precision is honest — and modest:

Country: reliable (95%+).
Region/city: good for fixed-line ISPs, fuzzy for mobile.
Exact address: essentially never. The tool shows a map link to the approximate location, not a doorstep.

Your "location" shifts when you switch networks, when your ISP changes routing, or when you use a VPN — because the IP's location is the network's location, not yours.

Timezone: a hidden consistency check

The timezone field is derived from the IP's location. It's one of the quiet signals anti-fraud systems use: if a login comes from a US IP but the browser claims a Dubai timezone, that's a mismatch worth flagging.

VPN and Tor detection

The tool reports isVpn and isTor — with an honest note that the field needs a paid threat-intel feed (ipinfo's security API, MaxMind's risk scores, or DNSBL-style checks) to be accurate. Free heuristics exist: known VPN exit ASNs, hosting providers that sell proxies, Tor exit-node lists. The giveaway pattern is usually an IP whose ASN is a cloud provider (AS16509 AWS, AS14061 DigitalOcean) when the user claims to be at home — cloud ASNs are a strong proxy for "this is a datacenter, not a person".

What you can do with this

Debug your own routing: see which country your traffic exits from and whether your ISP or VPN is doing something surprising.
Validate a server config: run the tool with any IP (the {ip} field) to check how an address classifies before you block or allow it.
Understand what others see: it's the same data a website's analytics gets when you visit.

curl -X POST https://yas.sh/api/v1/tools/what-is-my-ip -d '{"ip":"8.8.8.8"}'

Returns ASN AS15169, org Google LLC, city Mountain View, timezone America/Los_Angeles — everything a site knows about Google's resolver before you've sent a single byte of "personal" data. Your IP is public by design. Knowing what it says about you is the first step to deciding whether you care.
