AS8431 AS8431 Sofia, Bulgaria

AS8431 belongs to TEA Ltd of Sofia, one of Bulgaria's long-standing internet

companies. It sells business internet access in Sofia and Plovdiv alongside web

hosting, VPS, colocation and IT support. Many datasets show its name as *"Sofia,

Bulgaria"* — that is the registry's location field, not a company name.

What it's used for

• Corporate connectivity and hosted services. The reverse DNS across 195.230.0.0/19 is a roll-call of customer names: individual hosts and gateways under tea.bg are named after the businesses behind them, with the provider's own routers and address pools mixed in.
• Just under 5,000 IPv4 addresses in nine prefixes, all from a single legacy allocation, with no IPv6 announced.

Notable

• Business and hosting space, not eyeball space. There are no dynamic subscriber pools here. An address in this range is most likely a customer's server or a leased-line site.
• The AS peers with a large number of Bulgarian networks relative to its size, which is what a small local provider looks like when it sits on the national exchange: many peers, few upstreams, little address space.

Interesting

• The allocation's netname encodes its own date, 960917 — September 1996 — which is a fair marker of when this network first came online, back when a Bulgarian ISP named each customer's gateway by hand.
