Purchase a dedicated IP
Purchase a dedicated sending IP. Requires a verified or enterprise account. Telnyx allocates the next available IP from stock. The optional region and ip_version fields each restrict which stock IP is allocated; they never change the allocated IP’s metadata. An omitted field applies no restriction for that field, and omitting the body applies neither restriction. An unsupported selector value returns 422; a supported value that matches no available IP returns 429 and records the request on the waitlist. Billing: $14/month/IP, charged as a monthly recurring charge (MRC) from purchase. The IP is returned in provisioning status with a Telnyx-managed PTR hostname and carries no mail until you call start_warmup and add it to a pool that routes mail.
