IP Address (IPv4 / IPv6)

The numeric address that identifies a device on a network, which DNS maps a domain name to.

An IP address is the numeric label that identifies a device on a network — 93.184.216.34 in the older IPv4 format, or a longer hexadecimal string like 2606:2800:220:1:248:1893:25c8:1946 in IPv6, which exists because the world ran out of IPv4 space. The whole point of the DNS is to map a human-friendly domain to one of these addresses: an A record points a name at an IPv4 address, an AAAA record at IPv6. Blocks of addresses are allocated through IANA to regional registries. Domain tokenization operates a layer above all this — it changes who owns the name, not the addresses the name resolves to.

Author

Fenwei Bian is a software developer in her thirties who spends her working hours in pull requests and her weekends with her hands in soil or sawdust. Years of open source on GitHub taught her that names are interfaces: a good one is clear, honest about what it does, and kind to whoever has to use it next.

She gardens because it rewards patience and punishes wishful thinking, and she does woodwork because a joint either fits or it doesn't. Both habits show up in how she writes about naming — measure twice, check the source, and don't sand over a rough spot and hope no one notices.

For Namefi she writes about how domain markets actually move, the practical trade-offs of tokenizing and flipping names, and picking a domain you'll still be glad you own in twenty years.

Editor

Victor Zhou is a technology founder and standards editor focused on digital identity and trust. He founded Namefi, edits Ethereum Improvement Proposals, and previously led smart-contract architecture work at Google Labs.

His work sits at the intersection of naming, ownership, and the systems people use to establish identity online. That perspective makes him especially interested in the way names move between personal meaning, public recognition, and digital infrastructure.

For Namefi, Victor edits and writes about domains as durable digital identity: how names become ownable onchain assets, how tokenization changes custody and trust, and what naming can learn from the systems people use to establish identity online.
