  We prove some results on NIP integral domains, especially those that are
Noetherian or have finite dp-rank. If $R$ is an NIP Noetherian domain that is
not a field, then $R$ is a semilocal ring of Krull dimension 1, and the
fraction field of $R$ has characteristic 0. Assuming the henselianity
conjecture (on NIP valued fields), $R$ is a henselian local ring. Additionally,
we show that integral domains of finite dp-rank are henselian local rings.
Finally, we lay some groundwork for the study of Noetherian domains of finite
dp-rank, and we classify dp-minimal Noetherian domains.
