View your 128-bit IPv6 address or receive fallback status for IPv4 networks.
Click Copy IPv6 Address to copy your network address to your clipboard.
Queries native IPv6 endpoint headers to return your exact public 128-bit address in colon-separated hexadecimal.
Enables searching any IPv6 address to retrieve city, country, and ISP routing information.
All API results render inside browser memory. BunchTool maintains zero server logs of your public IP address.
IPv6 expands the internet address space from 32 bits (4.3 billion addresses in IPv4) to 128 bits (\(3.4 \times 10^{38}\) unique addresses), eliminating the need for Network Address Translation (NAT) firewalls on home routers.
An IPv6 address is formatted into eight 16-bit blocks written in hexadecimal (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334). Consecutive zero blocks can be compressed once using double colons (::).
During the transition phase, dual-stack technology allows devices to run IPv4 and IPv6 simultaneously. Testing your IPv6 address ensures your ISP and network infrastructure support next-generation routing protocols.
