utility like nslookup(1), but uses libnss_tls.so instead of DNS

 nss-tls is an alternative, encrypted name resolving library to use
 with glibc, which uses DNS-over-HTTPS (DoH).
 .
 The glibc name resolver can be configured through nsswitch.conf(5) to
 use nss-tls instead of the DNS resolver, or fall back to DNS when
 nss-tls fails.
 .
 This way, all applications that use the standard resolver API
 (getaddrinfo(), gethostbyname(), etc'), are transparently migrated
 from DNS to encrypted means of name resolving, with zero
 application-side changes and minimal resource consumption footprint.
 However, nss-tls does not deal with applications that use their own,
 built-in DNS resolver.
 .
 This package contains the utility program to lookup DNS names using
 libnss-tls.
