Summary
Gosfield North Communications
residential cable dsl isp
The AS handle AS-GOSFIELD is held by Gosfield North Communications Co-operative Limited.
What it's used for
- The address space carries residential and small-business customer traffic, evidenced by the reverse DNS record
dynamic-199-83-205-254.gosfieldtel.comand netnames such asGOSFIELD-1throughGOSFELD-4. - The AS announces 4352 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 12 observed neighbours; this ratio of address space to peering partners is consistent with a regional access network rather than a transit provider.

- The operator is a member-owned telecommunications co-operative based in Cottam, Ontario, providing internet, IPTV, and voice services over fibre and DSL infrastructure to the Cottam, Kingsville, and Essex area.
- The inventory consists of four distinct IPv4 blocks, including a /21 and two /22s, alongside a single /32 IPv6 prefix.

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 1,782 prefixes, as published 2026-10-16. 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.
