Cell C IP address & ASN guide
Cell C is South Africa’s fourth mobile operator. Since 2019 a large part of its customers’ traffic has been carried on roaming partners’ radio networks (MTN and Vodacom), but your internet traffic still exits through Cell C’s own core, so websites typically see an address from AS37168, Cell C (Pty) Ltd.
