 - The value of the `filter-addrs` parameter is a comma-separated list of network transport protocol _name strings_ as defined in the [multiaddr protocol registry](https://github.com/multiformats/multiaddr/blob/master/protocols.csv), e.g. `?filter-addrs=webtransport`.
 - `unknown` can be be passed to include providers whose multiaddrs are unknown, e.g. `?filter-addrs=unknown`. This allows filtering providers whose multiaddrs are unknown at the time of filtering.
 - Multiaddrs are filtered by checking if the protocol name appears in any of the multiaddrs (logical OR).
-- Negative filtering is done by prefixing the protocol name with `!`, e.g. `?filter-addrs=!quic-v1,!tcp`. Note that negative filtering is done by checking if the protocol name does not appear in any of the multiaddrs (logical AND).
+- Negative filtering is done by prefixing the protocol name with `!`, e.g. to skip IPv6 and QUIC addrs: `?filter-addrs=!ip6,!quic-v1`. Note that negative filtering is done by checking if the protocol name does not appear in any of the multiaddrs (logical AND).
 - If no parameter is passed, the default behavior is to return the original list of addresses unchanged.
 - If only negative filters are provided, addresses not passing any of the negative filters are included.
 - If positive filters are provided, only addresses passing at least one positive filter (and no negative filters) are included.
