nslookup works for me:

Win7 64-bit

$ nslookup leapsecond.utcd.org
Non-authoritative answer:
Server:  UnKnown
Address:  192.168.1.1

Name:    leapsecond.utcd.org
Address:  244.34.36.97

Win10 64-bit

C:\Users\Andy>nslookup leapsecond.utcd.org
Server:  UnKnown
Address:  192.168.1.1

Non-authoritative answer:
Name:    leapsecond.utcd.org
Address:  244.34.36.97

However,  tracert and ping  yield this on both W7 & W10:

$ tracert leapsecond.utcd.org
Unable to resolve target system name leapsecond.utcd.org.

$ tracert 244.34.36.97

Tracing route to 244.34.36.97 over a maximum of 30 hops

  1  Transmit error: code 1231.

Trace complete.

$ ping 244.34.36.97

Pinging 244.34.36.97 with 32 bytes of data:
PING: transmit failed. General failure.
PING: transmit failed. General failure.

Ping statistics for 244.34.36.97:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

Weird!
