*srclen*, an ``int``, the source prefix length, which is the
leftmost number of bits of the address to be used for the
lookup. The default is 24 for IPv4 and 56 for IPv6.
*scopelen*, an ``int``, the scope prefix length. This value
must be 0 in queries, and should be set in responses.

*text*, a `str`, the text form of the option.
Returns a `dns.edns.ECSOption`.
Examples:
>>> import dns.edns
>>>
>>> # basic example
>>> dns.edns.ECSOption.from_text('1.2.3.4/24')
>>>
>>> # also understands scope
>>> dns.edns.ECSOption.from_text('1.2.3.4/24/32')
>>>
>>> # IPv6
>>> dns.edns.ECSOption.from_text('2001:4b98::1/64/64')
>>>
>>> # it understands results from `dns.edns.ECSOption.to_text()`
>>> dns.edns.ECSOption.from_text('ECS 1.2.3.4/24/32')
