  Studies on neutrino-nucleon ($\nu N$) cross sections at different energy
scales have regained interest due to increasing importance of precision
measurements, as they are needed as an ingredient in all neutrino experiments.
In this paper we have calculated both charged current (CC) and neutral current
(NC) $\nu$N scattering cross sections at Ultra High Energy (UHE) regime in the
neutrino energy ($E_{\nu}$) region i.e. $10^{9} GeV \le E_{\nu} \le 10^{12}$
GeV using QCD inspired double asymptotic limit fit of electron-proton structure
function $F_{2}^{ep}$ to low $\mathit{x}$ HERA data. The form $F_{2}^{ep} \sim
x^{-\lambda(Q^{2})}$ used in our analysis, can be conjectured like a dynamic
pomeron (DP)-type behaviour. We also find an analytic form of the total cross
sections, $\sigma_{CC}^{\nu N}$ and $\sigma_{NC}^{\nu N}$ which appear to be of
hard-pomeron exchange types. A comparative analysis of our results with those
available in literature is also done. An improved understanding of $\nu N$
interactions at UHE are essentially important for future oscillation
experiments. Future measurements will support/confront our predictions.
