Summary

Gotham Web Services

United States · AI-generated

hosting business infrastructure

A whole block answering to another company's colocation name.

What it's used for

  • A web hosting company's network. 1,280 addresses across four IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Notable

  • All four blocks carry the netname GOTHAM-WEB-SERVICES and come from the same narrow range.
  • Every registrant field ends with a contact reduced to the single letter R.
  • Three of twelve sampled addresses answered, all with the identical name colo.synergylynk.com, which belongs to neither the AS name nor the registrant.
  • The AS first appeared in routing on 2000-10-31.

Interesting

  • One name repeated across a block, under a domain nobody else in the record mentions, is what happens when hosting space is resold. The company that owns the addresses is not the company whose brand the customers see, and the reverse DNS follows the brand rather than the ownership.
  • A contact field containing one letter is a registry record that lost its content somewhere between a form and a database. It appears on all four blocks identically, so it was filed once and copied, not typed four times.
  • Four blocks from one contiguous range that still need four separate announcements means the pieces were granted at different times with other holders taking the addresses in between.
  • Three upstreams for a hosting company is the right number: enough that losing one carrier is an inconvenience rather than an outage.

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 2026-10-21. 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.
