Summary

enterprise datacenter business

Thirteen prefixes, all carved out of one /16, announced separately from SAP's Walldorf site.

What it's used for

  • Corporate and datacentre connectivity. 15,104 addresses in thirteen IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

  • Every announced block sits inside 155.56.0.0/16 — from 155.56.192.0/20 down to three separate /24s.
  • All of them share the same netname, SAP, registered to SAP SE with Core Registry SAP SE as contact.
  • The AS handle is SAP_DC_WDF, and it carries an instruction: networkmail abuse to abuse@sap.com.
  • One address, 155.56.243.255, answers evaluate0766.me.sap.com.

Interesting

  • WDF is Walldorf, the town SAP is headquartered in, and DC is the datacentre there. The AS name is a site code, so the number identifies a building rather than the company.
  • Announcing thirteen fragments of a /16 instead of the /16 itself means the rest of that space is routed some other way. Every piece falls in the top quarter, 155.56.192.0/18, and each is sized to whatever it carries — a network with internal boundaries worth keeping visible from outside.
  • 155.56.243.255 looks like a broadcast address and is not one. It only would be if the block were a /24; the prefix actually announced is 155.56.240.0/21, and inside a /21 an address ending .255 is an ordinary host. Reading the last octet without the prefix length is how that mistake gets made.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
