AI analysis

ckw.ch is a parent of planauskunft.ckw.ch, webmail.ckw.ch, cedpki.ckw.ch, transfer.ckw.ch and feedback.ckw.ch, plus a few other host names.

ckw.ch refers to four IP numbers: 2606:4700:4407::6812:221b, 2a06:98c1:3105::ac40:99e5, 104.18.34.27 and 172.64.153.229.

Other host names, for instance alcaldialaromana.gob.do, sso-br.zetaapps.in, trockenbau.com, transunion.do.cdn.cloudflare.net and cedpki.ckw.ch share IP numbers with ckw.ch.

ckw.ch's delegation uses two name servers: grace.ns.cloudflare.com and merlin.ns.cloudflare.com.

ckw.ch uses the same name server setup as other domains, such as pillmayken.com.ar, altotraful.com.ar, vistasdelsur.com, hotelarcos.com.ar and brisasdemarazul.com.ar.

ckw.ch at least partially shares name servers with other domains, including a3qge91d.workers.dev, nl.bauhaus, telekom19.com.tr, 187.71.208.in-addr.arpa and tulogan.com.

These name servers are often used with chan.ns.cloudflare.com and sneh.ns.cloudflare.com.

Host names with six IP numbers:

grace.ns.cloudflare.com points to 2606:4700:50::adf5:3a9f, 2803:f800:50::6ca2:c09f, 2a06:98c1:50::ac40:209f, 108.162.192.159, 172.64.32.159 and 173.245.58.159.

merlin.ns.cloudflare.com points to 2606:4700:58::adf5:3bcd, 2803:f800:50::6ca2:c1cd, 2a06:98c1:50::ac40:21cd, 108.162.193.205, 172.64.33.205 and 173.245.59.205.

A single mail server handles ckw.ch, ckw-ch.mail.protection.outlook.com.
