MarsSeed [1] filed a deletion request for lib32-ldns [2]: Orphaned package, last updated in 2019. I suggest this can be deleted, as there are no AUR dependents. DNS server related libraries seem not to be needed in 32-bit on systems running x86_64 code. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-ldns/
