AI analysis

courses.ie is the parent of www.courses.ie.

courses.ie points to four IP numbers: 2606:4700:3034::6815:1bab, 2606:4700:3035::ac43:a996, 104.21.27.171 and 172.67.169.150.

For instance, other host names comail.pro, 70sz.net, soopage.com, boligmanager.com and enduel.bio share IP numbers with courses.ie.

courses.ie is delegated to two name servers: major.ns.cloudflare.com and tegan.ns.cloudflare.com.

courses.ie uses the same name server setup as other domains such as rioimob.com.br, onbrokers.com.br, casario.com.br, novaepoca.com.br and acesso.run.

courses.ie shares name servers with other domains at least partially, for example cscfg.ru, shoyu.co, breakingisraelnews.com, nashvilleaccess.com and ldxq.net.

Host names with six IP numbers: host name major.ns.cloudflare.com points to: 2606:4700:58::adf5:3bf1, 2803:f800:50::6ca2:c1f1, 2a06:98c1:50::ac40:21f1, 108.162.193.241, 172.64.33.241 and 173.245.59.241; host name tegan.ns.cloudflare.com points to: 2606:4700:50::adf5:3ae2, 2803:f800:50::6ca2:c0e2, 2a06:98c1:50::ac40:20e2, 108.162.192.226, 172.64.32.226 and 173.245.58.226.

Five mail servers handle courses.ie: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and alt4.aspmx.l.google.com.

courses.ie shares mail servers with other domains at least partially; for instance wondercide.com, gurumatatech.com, it-momonga.com, mariannevos.nl and kaityandkasey.com.

these mail servers are commonly used alongside aspmx2.googlemail.com and aspmx3.googlemail.com.

Host names with two IP numbers:

aspmx.l.google.com points to 2607:f8b0:4004:c19::1b and 172.253.62.27

alt1.aspmx.l.google.com points to 2607:f8b0:4003:c30::1b and 74.125.27.26
