Summary

delv cannot parse link-local ipv6 addresses with interface number

Steps to reproduce

• Fedora rawhide container via systemd-nspawn, with ipv6 enabled network provided by libvirt/dnsmasq
• Use systemd-networkd and systemd-resolved in container
• networkctl status

●        State: routable
       Address: 192.168.122.82 on host0
                169.254.76.164 on host0
                fc30:XXXX:XXXX:2b0a:3ccb:e4ff:fe52:caa8 on host0
                fe80::3ccb:e4ff:fe52:caa8 on host0
       Gateway: 192.168.122.1 on host0
                fe80::5054:ff:fe2b:eed3 on host0
           DNS: 192.168.122.1

• /run/systemd/resolve/resolv.conf is linked to /etc/resolv.conf
• /etc/resolv.conf has autoconfigured content:

  nameserver 192.168.122.1
  nameserver fe80::5054:ff:fe2b:eed3%2

What is the current bug behavior?

delv produces: delv

;; irs_resconf_load: invalid address format
;; resolution failed: not found

What is the expected correct behavior?

Skip address that cannot be parsed or even better parse it correctly

Relevant configuration files

• /run/systemd/resolve/resolv.conf

# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients directly to
# all known uplink DNS servers. This file lists all configured search domains.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 192.168.122.1
nameserver fe80::5054:ff:fe2b:eed3%2
