Name Servers

addcalc.net is delegated to two name servers: aragorn.ns.cloudflare.com and athena.ns.cloudflare.com.

addcalc.net uses the same name server setup as other domains such as treofinance.com, mailboxslots.com, financialplanninganalyzer.com, asthene.com and rksolar.net.

addcalc.net shares name servers with other domains at least partially, for example nationaltriallawyers.net, v2x.network, traveltomyanmar.com, mgb.bg and bwscores.com.

These name servers are commonly used with rocco.ns.cloudflare.com.

Host names with six IP numbers: host name aragorn.ns.cloudflare.com points to: 2606:4700:58::adf5:3b43, 2803:f800:50::6ca2:c143, 2a06:98c1:50::ac40:2143, 108.162.193.67, 172.64.33.67 and 173.245.59.67; host name athena.ns.cloudflare.com points to: 2606:4700:50::adf5:3a48, 2803:f800:50::6ca2:c048, 2a06:98c1:50::ac40:2048, 108.162.192.72, 172.64.32.72 and 173.245.58.72.
