DNSReport says "All nameservers respond" and mentions "dns2.webhosting-ace.co.uk. | 64.120.176.243".
But nslookup using that IP address as server fails:
# nslookup uncommercial.co.uk 64.120.176.243
;; connection timed out; no servers could be reached
Another testing service correctly identified that 64.120.176.243 was not responding to tcp or udp DNS requests. (The IP address was out of date and has now been corrected).
