💖 ldns-update — the manual, but make it cute 💖

okay so bestie, welcome to ldns-update(1) — it's a General Commands Manual page, and honestly? it's short, it's sweet, it does exactly one thing and it does it slayfully. let's get into it 💅

✨ NAME ✨

ldns-update — send a dynamic update packet

like... that's the whole job. send a dynamic update packet. iconic behavior fr fr 🌸

---

🦋 SYNOPSIS 🦋

ldns-update name [ zone ] [ ip ] [ tsig_name tsig_alg tsig_hmac ]

so name is required, and then zone, ip, and the trio tsig_name tsig_alg tsig_hmac are all optional. the brackets are literally telling you "these are optional bestie, add them if you need them" 💜

---

👑 DESCRIPTION 👑

ldns-update is used to send a dynamic update packet.

that's it. that's the vibe. it sends a dynamic update packet, no cap ✨

---

🎀 OPTIONS 🎀

• name — the domainname to associate with the given ip address. like, "this name goes with this IP", match made in heaven 🫶
• zone — when you give this, it uses this zone instead of trying to find and process the domain's SOA record. so it skips the whole "let me go hunt down the SOA" side quest and just uses what you told it 🧚
• ip — send the update to this IP address. but — and this is the spicy part — when the literal text none is given, it removes any previous addresses. yes, literally the word none, not an actual IP. so none = delete the old ones, periodt 💀
• tsig_name tsig_alg tsig_hmac — use TSIG (rfc2845) to authenticate. that's your name, your algorithm, and your hmac, all three together as a little squad 🔥

🌈 EXAMPLE 🌈

ldns-update my.example.org 1.2.3.4
