Description-en: 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.
