OSIN- But at this website we learn that ISIRAN is actually a subsidiary of a conglomerate called Iran Electronics Idustries. This seems to be a company heavily tied to the Iranian military. And some Ministry of Defense (MOD) websites fall in this IP block, especially on subnet 32. This block also allows a lot of reverse-DNS lookups, which is unusual for Iranian blocks.
