Verisign Registry Infrastructure Domain

nstld.com is the nameserver infrastructure domain operated by Verisign, Inc., the authoritative registry operator for the .com and .net top-level domains. The name "nstld" stands for Network Solutions Top-Level Domain, a legacy reference to Network Solutions, the original .com registry operator before Verisign acquired that business in 2000.

Purpose

This domain does not host a website—it exists solely to provide authoritative nameserver hostnames for Verisign's domain registry infrastructure. The four nameservers (av1-av4.nstld.com) serve as authoritative DNS for domains managed by Verisign's registry services.

Technical Infrastructure

• Nameservers: av1.nstld.com, av2.nstld.com, av3.nstld.com, av4.nstld.com
• Network: All nameserver IPs are within Verisign's autonomous system (VERISIGN-AS)
• Mail: Handled by Verisign's corporate mail servers (eagle.verisign.com, pigeon.verisign.com, citadel.verisign.net, kaos.verisign.net, modor.verisign.net)
• DNSSEC: Not signed (no DS record)
• Contact: nstld@verisign-grs.com (Verisign Global Registry Services)
