AI analysis

cnx.org is a parent of blog.cnx.org, jenkins.cnx.org, devblog.cnx.org, mx01.cnx.org, prod00.cnx.org and a few other host names.

cnx.org maps to four IP numbers: 3.167.99.13, 3.167.99.21, 3.167.99.89 and 3.167.99.118.

Other host names, for instance klimafolgen.com, si-ran.com, cbt231.com, d12nxawneft9rz.cloudfront.net and d29px4l61l2ylm.cloudfront.net share IP numbers with cnx.org.

cnx.org's delegation is handled by four name servers: ns-267.awsdns-33.com, ns-698.awsdns-23.net, ns-1450.awsdns-53.org and ns-1862.awsdns-40.co.uk.

cnx.org partially shares name servers with other domains; examples include lesbertarian.com, sec.nikecloud.com, cambridge-machines.com, d2rwfhkeczrx15.cloudfront.net and tradimo.es.

These name servers are commonly paired with ns-1460.awsdns-54.org, ns-425.awsdns-53.com, ns-530.awsdns-02.net, ns-541.awsdns-03.net, ns-1175.awsdns-18.org, ns-1906.awsdns-46.co.uk and ns-585.awsdns-09.net.

Host names with two IPs:

ns-267.awsdns-33.com points to 2600:9000:5301:b00::1 and 205.251.193.11

ns-698.awsdns-23.net points to 2600:9000:5302:ba00::1 and 205.251.194.186

ns-1450.awsdns-53.org points to 2600:9000:5305:aa00::1 and 205.251.197.170

ns-1862.awsdns-40.co.uk points to 2600:9000:5307:4600::1 and 205.251.199.70

Five mail servers handle cnx.org: 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.

cnx.org shares some mail servers with other domains, at least partially, such as ns500731.ns500731.ns500731.ns500742.ns500754.ns500671.ns500688.ns500678.ns500678.ns500688.ns500131.lustychickser.com, ns500758.ns500758.ns500698.ns500735.ns500736.ns500735.ns500735.ns500736.ns500698.ns500698.ns500708.ns500708.ns500619.ns500576.trackreceptor.com, ns500731.ns500754.ns500742.ns500754.ns500731.ns500742.ns500678.ns500678.ns500649.ns500291.ns500666.ns500142.lustyslutz.com, primoengineering.com and ns500671.ns500742.ns500731.ns500754.ns500704.ns500742.ns500688.ns500688.ns500704.ns500678.ns500671.ns500688.ns500291.ns500671.ns500666.ns500153.tenderladiesbz.com.
