Verisign operates j.root-servers.net, one of the thirteen logical Internet Root name servers. Verisign cooperates with the eleven other Root Server Operators to provide authoritative data for the DNS Root Zone.
J-root receives DNS queries over IPv4 at 18.104.22.168 and over IPv6 at 2001:503:c27::2:30.
J-root uses IP Anycast to provide service from a large number of locations throughout the world, which may change from time to time.

In 1997, j.root-servers.net was added as the 10th root name server. Operated by Network Solutions, it was initially co-located with A-root and used the IP address 22.214.171.124.
In 2000, Network Solutions, Inc. was acquired by Verisign.
In 2002, J-root was renumbered to 126.96.36.199, thus allowing it to be anycasted.
In 2008, the IPv6 address 2001:503:c27::2:30 was added for J-root.
