IR-SEPANTA is operated by Sepanta Communication Development Co. Ltd.

What it's used for

  • The address space carries subscriber access traffic, evidenced by reverse DNS entries such as 85.133.187.254.pos-1-0.7tir.sepanta.net and 85.133.129.255.sepanta.net.
  • The AS announces 16,128 IPv4 addresses across 28 prefixes and 1 IPv6 prefix, while maintaining only 3 observed routing neighbours.
  • This high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider, consistent with Sepanta's role as an internet service provider in Tehran.

Notable

  • Registrants for the largest prefixes are listed as "Public Role" or "Sepanta Communication Development Co. Ltd", aligning with the AS holder.
  • The inventory consists primarily of /22 and /23 blocks within the 85.133.0.0/16 range, with a single /20 block.
  • The network has been visible in routing tables since 2006.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
