Analysis
Name Servers
Two name servers handle the delegation for express-scripts.md: ns2.cigna.com and ns.cigna.com.
express-scripts.md shares its NS records with other domains, for example cigna.world, cignamedicareaccess.com, hepcaccredo.net and two others.
There is at least partial name server overlap between express-scripts.md and other domains — tghecignagroup.com, cignahealthcae.com, theciwnagroup.com and two more among them.
These name servers are routinely deployed together with the name servers dns-publicprimary-wdc.sys.cigna.com.
ns2.cigna.com → 170.48.24.5 and ns.cigna.com → 170.48.11.4: one IP number per host name.
